Super Mario 3D World: Star-8 -- Peepa's Fog Bog

The first part of this level is a graveyard covered in snow. There are Key Coins to collect. Some of them are not as obvious to reach. One on the left is above invisible clouds. One in the center requires hitting a POW Block. Go through the front right door to reach the Key Coin on the balcony. Dodge the many Peepas (ghosts) and Snow Pokeys. Towards the back are two headstones with glowing spots you should ground pound. The one on the right has a Starman. Get it and run to the back left corner to defeat the Peepas surrounding Captain Toad for the first Green Star. The headstone on the left has a Fire Flower. Once you collect the Key Coins, take the warp box to another area.

The warp box takes you to a raft on purple water. Grab the clock and the raft will drop you off at the midpoint. There are many Boos in the fog. Narrow wooden planks rise in and out of the fog. Memorize the path so you know which way is safe. On solid ground, you'll see two Mystery Boxes. The left one is fake. The right one leads you to a room where the second Green Star will disappear if you approach it. Quickly throw a snowball at it to get it from the stone tiles. The third Green Star is nearby, out over the fog. Grab a snowball from a Snow Pokey and throw it at the Green Star. Farther along, you'll find a boost pad. Make sure the path ahead is about to appear before you hit it and start running. Take the path to the right for the stamp. The warp box ahead takes you to the flagpole, where there are Peepas and invisible clouds.

The stamp is of Cat Rosalina.

Super Mario 3D World: Star-5 -- Super Block Land

The level is filled with giant blocks. There's a Tanooki Suit  in one of the item blocks. Just to the right of the giant brick blocks, on the right side of the tall wall, is an invisible block with a Mega Mushroom. You'll have to use a Bob-omb to clear the giant brick blocks in the way. This makes clearing the path ahead a little easier, since there are several Chargin' Chucks. It also makes getting the stamp easier. Go all the way to the right and you'll find a lone brick block in the lower right corner. Destroy it with the Mega Mushroom, or ground pound it for a while as long as you're not small. The stamp is in the alcove behind it. Nearby are four giant item blocks. Pound them to form a path to a Mystery Box. Inside, pound the right giant item block to reach the first Green Star. The warp box is to the right.

Slide down to the midpoint, behind the POW Block. Use a Bob-omb to destroy the brick blocks in the ground to reveal a springboard. Up ahead and to the left is a gray brick. Use a Bob-omb to destroy it for the second Green Star. On solid ground, you'll find Key Coins and more Chargin' Chucks. Most of the Key Coins are visible and easy to reach. One is under some brick blocks near the back wall. Use a Bob-omb to reach it. Go to the far right and destroy the large brick block. Pound the giant item block to reach the third Green Star. The unlocked warp box will take you to the flagpole. Giant item blocks will form a path to the flagpole when ground pounded.

The stamp is of Tanooki Luigi.

Super Mario 3D World: Star-3 -- Rolling Ride Run

You'll want to be Rosalina for this level. There are large cylinders in this level that roll along across large gaps. You have to propel them by standing on the edge of the direction you want to go. It's log rolling. Cross the first gap, go past the Goomba, and you'll see another cylinder. On the back wall are some brick blocks. In the second set of brick blocks, you'll find a Boomerang Flower. Roll the front cylinder to the right and you'll pass an alcove with a Mystery Box. Run around the inside of the cylinder to rotate it so you can reach the first Green Star. Transfer cylinders and roll pass the Conkdors. Kill them with the boomerang to make your life easier. The warp box is to the right.

The warp box takes you to the midpoint. Up ahead are Conkdors on cylinders. Spinning the cylinder will not make them fall off. On the wide cylinder to the right, move towards the screen to find a narrower cylinder with the second Green Star. Farther ahead is a large cylinder. Use the boomerang to clear out the pink wall enemies so you can walk around the obstacles. Roll the cylinder to the right so you can walk around the corner, then walk towards the screen. There's an invisible block with a Double Cherry. Roll the cylinder to the right a little more, then walk towards the screen to solid ground. You'll find some clocks as well as a button with a Grand Star symbol. Have Rosalina stand on it for the stamp. Follow the maze while rolling the log until you reach a two-person platform. This will take you to the third Green Star and a clock. Alternatively, you can reach it with a Super Bell if you have one. To the right is a roller to the flag.

The stamp is of small Rosalina spinning.

Super Mario 3D World: Bowser-6 -- A Beam in the Dark

This level is a Ghost House that introduces the Light Box. You'll want Luigi for this level. Shine the light on Boos and ghosts for a long enough time to defeat them. Stand on the circular platforms on the floor to make it move. Shine the light to clear the path ahead of you. To the left is a Luigi switch with the stamp. Get back on the platform and it drops down when a giant Boo appears. You'll land in front of a mirror. The first Green Star appears in the mirror, so walk towards the screen to get it. Up ahead is another circular platform. Ride the platform and hit the POW Blocks for more light for a short time. It will also temporarily stop the Para Dry Bones. There's a Red Coin Ring ahead if you like. At the end of the ride is a door to the midpoint.

Go to the back wall and take the elevator up. This takes you to a hall of Bowser statues. The platform will quickly move forward. There's a gap in the statues on the right side, about halfway. Jump to the right to find a Mystery Box. It will take you to a room with six Boos. Kill all of them with the Light Box to get the second Green Star. Take the door behind you to reach the back wall. There are several doors here. Go through the right door, which takes you to the upper level. Take the middle right door to move forward. Once again you have to ride a platform, but it is broken into more of an hourglass shape. Do your best to survive all of the ghosts and Para Dry Bones without falling off. At the end is a giant Boo guarding the third Green Star. Either kill it with light or lead it away. Go through the door to the right. A platform will drop you right in front of the flagpole.

The stamp is of small Mario tripping and falling.

Super Mario 3D World: Bowser-4 -- Footlight Lane

The calm music of Puffprod Peaks is back. There's a large gap between platforms, with Thwomps floating over the gaps. When they land, the path is revealed. It will also appear if you approach the edge of a platform, if it is nearby. More of the path becomes visible with impact, so pound the ground to see where you are going. Some paths have gaps in them, so do not rush ahead until you know where the path leads. Also in area are Para Dry Bones. Get a Boomerang Flower from one of the item blocks. On the third platform is an invisible triple item block with a Starman. Use it to get rid of the Para Dry Bones. The first Green Star is floating near the Para Dry Bones. It's floating over a part of the path, so you can jump to it or use a boomerang. The path to the left leads to the midpoint.

Up ahead are spike bars spinning in circles. The path goes around the circles' outer edges, but the first two circles have hollow centers. The third circle has a filled center and a Green Ring. Grab the Green Coins by following the outer spike bars for the second Green Star. Past the second Green Star, you'll find Bullet Bills. If they explode near the path, more of it will be revealed. Some of the Bullet Bills are Cat Bullet Bills, which follow you. After the first set of Bullet Bills is a platform with a glowing spot. Pound it, and you'll see part of the path appear to your right. Follow it to the stamp. Farther ahead and to the left is a Mystery Box. There is a Thwomp over an invisible path. Stand on it and it will take you to the level of the third Green Star. Carefully follow the path ahead to the warp pipe. There is a path forming stairs to the flag.

The stamp is of a Bullet Bill.

There is a nearby Sprixie House. The stamp here is of the red Sprixie Princess.

Super Mario 3D World: Bowser-3 -- Cookie Cogworks

This level is made of sweet treats and there are spinning gears here made of cookies. You'll want Peach for this level. Running on the gears are spiky mice. They will periodically jump, so jump over them after they land. Drop down after the first couple of gears. Down here, you'll find a giant Piranha Plant and a Boomerang Flower in an item block. To the right, jump up the gears, then jump on the large gears. Jump up and to the left and use the boomerang to get the first Green Star. Go to the right for a clear pipe to the midpoint.

On the back wall are more gears. Some parts of the cogs have Piranha Plants on them, so time your jumps. At the top are two giant Piranha Plants in front of a pipe. At the top rows of spiky ants. A Boomerang Flower follows them. The stamp is below. You can clear out the ants with the boomerang, then drop down to get it. Alternatively, you can wall jump around the back wall in the corner to find the clear pipe that goes between here and the stamp. Up ahead are more mice running on gears and more ants. Below these ants is a Mystery Box. It will take you to a spinning cylinder. Run so you don't fall off, but stay on the right side. The second Green Star will appear on the right side. Once out of the Mystery Box, go past the mice on the descending gears and you find a pipe that leads to the flagpole.

Go past the flagpole and you'll see an island in the distance. Get a running start and jump, then float down to the island. There are coins, a clock, and a bunny. Catch the bunny, who jumps on the central cog, for the third Green Star. The pipe will take you back to the flagpole.

The stamp is of Boomerang Toad.

Super Mario 3D World: Bowser-1 -- Spiky Spike Bridge

When Bowser took all of the Sprixie Princesses at once, he created a clear pipe to his own world, World Bowser. It's a large amusement park.

In this level, it's rainy and dark. Most of the path is covered in spikes. Sometimes, the spikes appear in a sequence instead of all at once. There are parts of the level not covered in spikes. One area has a Para Dry Bones and a Super Bell. Cross the spikes ahead to a warp box. Up ahead are long stretches of spikes. In one corner is a Fire Bro. Go left of the Fire Bro and climb up the wall for the first Green Star. Past the Fire Bro are moving bridges with spikes. Use the POW Blocks to get rid of the Para Dry Bones for a short time. The warp box ahead leads to the midpoint.

Past the midpoint is a warp box that leads to an area with more spikes. Go to the left for the stamp. Return, jumping over the spikes. In the middle is another Fire Bro. Climb up the tower for a Mystery Box. In the Mystery Box, climb the wall and drop down to the P-Switch. This makes the second Green Star appear. Climb back up the wall and jump over the right wall to get the Green Star. At the end of the long stretch of spikes is a warp box. This will take you to an area with many Para Dry Bones. Grab the Starman in the item box to get rid of them. To the left is the third Green Star on some donut lifts. Wait until the floating platform with spikes is approaching and close to get the Green Star, then jump onto the platform. Dodge the sequential spikes, then transfer to another platform with spikes. This one will take you to a warp box to the flagpole. There are spikes on the stairs.

The stamp is of a Para Dry Bones.

Super Mario 3D World: Castle-4 -- Boiling Blue Bully Belt

This level has stone platforms with arrows appearing from and disappearing into blue lava. The platforms with the arrows will allow to cross the lava, but you have to be quick about it. You'll find Bullies and Para Dry Bones here. There's a Green Ring near the lava. The Green Coins will appear on the arrow platforms. Ahead is a large patch of lava. There are spinning spike bars here. Follow the platforms with arrows, and go left past the first set of spike bars. You'll find a stone platform with the stamp. Stay on the platform if you can't reach the arrow platforms. To the left of the four spinning spike bars is a Mystery Box. Pound the Bully into the lava within the time limit to get the second Green Star. Use the arrow platforms to reach the midpoint on solid ground.

Up ahead, platforms slide in and out of the walls. Use them to reach the cylinders, but beware the spike bars moving over the cylinders. The third cylinder has the third Green Star on the side away from the wall. That part of the cylinder also has a spike bar. Past the fourth cylinder is a pipe that leads to an area with three Bullies. The area tilts in the lava. Kill them for a platform to the flag. Arrow platforms will appear from the lava to make stairs to the flag.

The stamp is of a brick block.

Super Mario 3D World: 6-6 -- Bullet Bill Base

Bullet Bill Base is a tall tower. There are moving clouds here as well as many Bill Blasters. Grab a Super Bell and go to the wall that's moving up. Climb up it and the nearby clouds to reach the first Green Star at the very top. Go below the level with the crates for the warp box to the midpoint. Climb the back wall for a Mystery Box. Climb the wheel to reach the second Green Star. When you return to the main level, you'll find moving Bill Blasters to dodge. In front of the wall to the right, is an invisible block with a 1-up high above. Ahead are moving clouds and walls, as well as a Banzai Bill. Take the moving walls up and to the right for the third Green Star. Up and to the left, you'll find the stamp over some brick blocks. Go to the right and you'll find the flag.

The stamp is of a defeated Goomba.

Super Mario 3D World: 6-5 -- Ty-Foo Flurries

Ty-Foos are giant Foos that blow vortices. They're strong enough to push you to the edge of the ground. There's lots of snow in the area. You may want Toad for this level. The first set of item blocks has a Fire Flower. Hit the Ty-Foos with it to temporarily stun in so you can pass. Go right and up the path with the crates. You'll find a couple of brick enemies with spiked edges that will strafe side to side. Past them is some ice with a Goomba in a Kuribo's Skate. Take the skate and use it to safely go onto the spikes ahead and reach the stamp. Return to the ice, then go up the steps. There are Ty-Foos here. There are a couple of item blocks in the path of a Ty-Foo. Above them is an invisible block. Stand on it to reach the first Green Star. Ahead is a narrow path with several Ty-Foos. Either run quickly or stun them individually to pass. Go through the clear pipe at the end to reach the midpoint.

Past the midpoint is more ice. Grab a Kuribo's Skate and go left to the Mystery Box, crossing some spikes. Here, grab another Kuribo's Skate and skate downhill as quickly as possible to reach the second Green Star. Once you return to the main level, cross the spikes again, then go to the back wall. The third Green Star is in the gap. Jump into the gap when you see a little air current come from the gap. A vortex will push you out of the gap. Don't jump when the vortex is there or you won't be able to reach the Green Star. Ahead are more Ty-Foos and brick enemies, which makes reaching the pipe to the flag difficult. Time your movements and proceed with caution.

The stamp is of Mario and Kuribo's Skate.

Super Mario 3D World: 6-3 -- Hands-On Hall

You'll need 100 Green Stars to unlock this level. This level takes place inside and outside a Japanese-style house with music to match. You'll start in an empty hallway. Touch what looks like the back wall using the Game Pad to make the doors slide open, revealing a pipe. Go through the pipe to a room with Goombas. Get a Boomerang Flower from the item block. You can now throw boomerangs, which give you a range attack with the potential for combos. Touch the door to the right and go behind the wall. Go all the way to the right and you'll find an invisible block with an item in it. Go back left and open the door. Carefully go up the ramp, as there is a Spike throwing spike bars down the ramp. Go left and open the doors to reveal two P-Switches. Take out the Galoomba before it hits you. The left P-Switch lowers the stairs to the left. The right P-Switch makes two Goombas appear. Kill them for Goomba Caps. When wearing the Goomba Cap, enemies will not notice you. If you run into an enemy, you'll lose the Goomba Cap.

Go up the stairs and ring the gong (by touching it on the Game Pad) for lots of coins. Ahead are more sliding doors. The first Green Star is behind these doors, but you have to wait for the wall to move first. Just ahead is a clock and an invisible Moneybag. To the right is the warp box behind some doors with many Goombas to the midpoint, which is outside. This is part of the building's roof. There are Thwomps, Spikes, Goombas, and Key Coins here. The second Green Star is nearby, in the gap to the right. Jump the gap or use a boomerang to get it. On the other side of the gap are Propeller Blocks. When wearing them, press (A) to jump, then hold (A) to fly. You can only wear one item at a time, so if you want the Propeller Block, lose the Goomba Cap by taking damage. The five Key Coins are all over here, but not hard to find. Check the top levels of the roof if you're missing any. The warp box is on the top level.

The warp box takes you back inside. Ringing the first gong makes Goombas appear, but the second one makes coins appear. Ahead, you'll run into a few sets of Spikes. Kill the first three you find. Walk towards the front wall, where the spike bars were going and you'll wind up outside. If you still have the Propeller Block, fly up onto the roof and you'll find the stamp on a cloud. It's well hidden. Carefully drop down and go back inside. There are more Spikes inside. To the right, you'll find a warp box and a gong. Ring the gong to make a Mystery Box appear. This takes you almost outside, where a Spike is waiting in a cage on the side of the building above where the Thwomps were. Kill the Spike for the third Green Star. Go through the warp box, which takes you to the roof and the flagpole. There are golden Cheep-Cheep statues. Hit the triple item blocks under the Spike to defeat it, allowing you to reach the flag more easily.

The stamp is of a Moneybag.

Super Mario 3D World: 5-7 -- Searchlight Sneak

This is a stealth level. It looks like a castle level. Avoid the spotlights or an alarm will sound and Cat Bullet Bills will be fired and home in on your location. Grab a Tanooki Suit from the item block near a spring enemy. You'll cross a gray brick floor. Be careful about avoiding the spotlights as the Cat Bullet Bills can destroy the bricks. Past the long stretch of gray bricks, you'll find the first Green Star high above the solid floor in the path of a moving spotlight. Use the spring enemies to get it.

When you're past the spotlights circling each other, go behind the wall to the midpoint. You'll be hiding from the spotlights behind the walls. Another spotlight illuminates the stamp over some brick and item blocks, so be careful when you try to get it. There's a crack in the wall. Lead a Cat Bullet Bill to the crack to reveal a Mystery Box. There are brick stairs to the second Green Star. Cat Bullet Bills will appear and destroy the bricks. Move quickly. There are Red Coins ahead if you want them. Climb up the stairs and lead the Cat Bullet Bills to the third Green Star, which is surrounded by bricks. The Cat Bullet Bills will break the bricks so you can reach it. At the top of the stairs is the flag.

The stamp is of Toad jumping.

Super Mario 3D World: 4- Castle -- Lava Rock Lair

You need 50 Green Stars to unlock this level. The castle is filled with lava and Brolders. You can pick up the Brolders and throw them around. Throw one on the P-Switch to lower a bridge to the first Green Star. Cross the gaps with the Podoboos and you'll see a Red Coin Ring. The Red Coins will appear over or between brick blocks. To reach the highest ones, throw a Brolder onto the brick blocks to collect them. This will give you a Super Bell. Try to keep it. Take the pipe under the lava with the Podoboos and you'll come out near a Mystery Box. The Mystery Box has three P-Switches and two Brolders. You have 10 seconds to put a Brolder on two of the P-Switches, stand on the third, and collect the Green Star. This may take a while unless multiple people are playing.

Just past the Mystery Box is a tall wall. As a cat, you can climb up the left wall for the stamp. Ahead are some Goomba stacks and Brolders appearing out of the ground. One Goomba stack has a Super Bell. The third Green Star is on the left side, over the lava. Toss a Brolder to get it. At the back is an invisible block with a Super Mushroom and a pipe.

The pipe leads to the battle arena, which is surrounded by lava. Walk to the center and a crystal Brolder called Boss Brolder will appear, with three normal Brolders. Pick up a Brolder and toss it into Boss Brolder. After a hit, Boss Brolder will roll around, chasing you. Hit Boss Brolder three times to win. A warp box to the flagpole will appear. Free the orange Sprixie Princess and she'll use a pipe to build you a clear pipe to World 5.

Super Mario 3D World: 4-4 -- Big Bounce Byway

This level is filled with orange bouncy platforms and Biddybuds. Bounce up the wall using the moving orange platforms. On top is a large orange platform where you can find Spinies and Red Coins. On the left wall, you'll find a few clocks. Bounce up to find some spring enemies. One of them will temporarily turn into a spring you can pick up and use. Put it down periodically and stomp it so it doesn't become an enemy again. It will turn into a spring again if you stomp it. Use it to reach first Green Star on the back wall. Pick it up and cross the moving orange platforms that tilt.

The midpoint is here. Behind the midpoint are a set of rising bouncy platforms. Use the spring to reach them to get the second Green Star. To the right, you'll find a Mystery Box. There are a few spring enemies in the box. The one to the right will become a spring so you can reach the third Green Star. Once out of the Mystery Box, bounce on the large orange platform. It will start moving on a path, taking you through some groups of Biddybuds. In the large circle of Biddybuds is the stamp. The warp box to the flag is on a cloud at the end. There are spring enemies near the flagpole to help you reach the flagpole.

The stamp is of a Super Mushroom.

Super Mario 3D World: 4-2 -- Piranha Creeper Creek

The water here is purple, so don't fall in. There are Piranha Creepers here, Piranhas on vines that will move around if they're not asleep. Stomp on them or use fireballs to make them retreat. If they retreat all the way to the hole they're hiding in, they'll be defeated. You'll need to do this to access the pipe ahead.

The pipe takes you inside a cave. There's a Mystery Box in the back wall. It leads to a room with four sleeping Piranha Creepers and the first Green Star. Bounce on each Piranha Creeper in quick succession to reach the Green Star. Keep going and you'll reach the midpoint. There's some regular water in the cave. Drop down where there are two Piranha Creepers moving over the same platform. At the bottom is the second Green Star. Up ahead is a Piranha Creeper on the wall. You can either ignore it or jump on it and run behind the wall for many coins and the stamp. You can also go underwater and access the stamp from the other side. Go through the pipe.

The pipe takes you back outside, where there is a random item block in front of a purple waterfall. Circular platforms fall from the waterfall and float along to the edge, where they fall off. Cross them to reach two wooden platforms with sleeping Piranha Creepers. There's a Green Coin Ring here. Collect all 8 Green Coins for the third Green Star. The pipe at the end takes you to the flagpole, where there's a sleeping Piranha Creeper in front of the flagpole.

The stamp is of a pipe.

Super Mario 3D World: 3-6 -- Mount Must Dash

There's a pun in the title and original Super Mario Kart music from Mario Circuit here. Instead of driving, you'll be running around the track. Climb up the trees for a Super Bell. There are boost pads to speed you up, sometimes directly in the path of enemies. You'll have to attack to avoid taking damage. Dodge the Biddybuds and take the lower path with the donut lifts when the path splits. You'll find the first Green Star here. The top path has Piranha Plants. At the end of the track is a warp box. Go through it.

The warp box takes you to the top of a slide. You can slide into the Biddybuds to defeat them. At the bottom of the slide is the midpoint. Run up the hill and you'll see gaps with bouncy pads in them. Drop down into the second gap to reach the Mystery Box. You'll end up in a room with boost pads and a bunny. Use the boost pads to chase down the bunny for the second Green Star. Just be sure you don't end up on a boost pad in a corner. Jump to get out of it. When back on the main track, keep going and boost to a springboard. This will take you to some orange bouncy pads with the stamp. Slide down the slide and you'll find Piranha Plants at the bottom with the warp box. Ignore the warp box for now and climb up the wall behind it as a cat for the third Green Star.

The warp box takes you to another part of track. Run up the track, then slide to the flagpole.

The stamp is of a bunny.

Super Mario 3D World: 3-3 -- Shifty Boo Mansion

It's time for the first Ghost House. You can see Big Boo outside, peering through the windows. There are lots of Boos here and the floor and furniture move. There are some moving triple item blocks. Use them to reach the triple item block above for a Fire Flower. Fireballs won't defeat the Boos, but they'll become temporarily transparent, allowing you to walk through them. Go up the stairs and you'll see a portrait of a Boo. Jump into the portrait, which has a Mystery Box behind it. It takes you to a rotating room with ghosts. Wait until the room rotates far enough that you can get the first Green Star. Keep going and you'll see a couch. Stand on it and it will float up to the stamp. At the end of the hallway is a door to the library.

The shelves of the bookcases move when you stand on them. In the lower left corner of the bookcase is the second Green Star. It is hidden behind one of the shelves. Stand on the shelf above it and they will slowly move out of the way. Go up the bookcase shelves to reach the midpoint. There is an invisible block on the back wall so you can reach the item block with another Fire Flower. Go to the right, then go toward the front wall (towards the screen). There are invisible clouds that lead to a 1-up. On solid ground, Big Boo will chase you up the moving steps. Go to the right and pass the pipe, which is fake. Go up the left stairs for a clock. To the right, there is a door near a gap. In the gap are invisible clouds with coins. The door takes you outside.

There are many ghosts out here moving around. The 1-up is fake. Go through the door to go back inside. The floor is moving to the left. There's a clock nearby if you ant to risk it. Keep going to the right and you'll find another couch. It will float to a fake pipe which contains the third Green Star. The door will take you outside again, but the floor is moving to the left. Two Big Boos will chase you, so run quickly. Go past the flagpole, as it is fake. The Big Boos will leave you alone and you'll soon come across the real flagpole.

The stamp is of a Boo.

Super Princess Peach: 2-3 -- Shadow-Play Alley

In the first part of the level, you can see yourself, but the shadows are very prominent. Get a Super Bell and pick up a Potted Piranha Plant, which will eat anything in your way, and pick up things for you, such as Green Stars. You'll encounter Fire Piranhas and Fuzzies. Have the Potted Piranha Plant eat them. Go to the right and you'll see the shadow of a Green Star. Walk towards the front wall and you'll find the area extends far forward. Keep going to reach the Green Star. If you stand on the platforms near the front wall, you may find something. Soon, you'll find a midpoint and a door.

The door leads to the other side of the gap, but now all you can see is shadow, making the area 2D. You'll get another Potted Piranha Plant to use on the Fuzzies. Ahead is a Giant Piranha Plant. Stomp it, then drop down and use your claws to reach the stamp below. There are crates that look like walls are blocking your way. At the end of the area is a door.

The door will bring you out of the shadows. Pick up another Potted Piranha Plant. There are pink enemies covering part of the wall. Tap them on the touch screen or have the Piranha Plant eat them. Behind them is a Mystery Box. Hit the P-Switch on the stairs to reveal that the second Green Star is hidden under the stairs. Drop down, then go left to get it. Pick up the Potted Piranha Plant again and have it eat the Fuzzies. Go past the next door you see. You'll find Captain Toad cowering near the shadow of Bowser. Walk towards the front wall to reveal that it is really animatronic cardboard. Use your claws, fire balls, or just knock it over to destroy it. Captain Toad will give you the third Green Star. Go through the door to reach the flagpole.

The stamp is of the Potted Piranha Plant.

Super Mario 3D World: 1-5 -- Switch Scramble Circus

To get through the circus, you'll have to touch all of the blue switches to turn them yellow. Once they're all yellow, they'll turn green and the wall in front of you with the card suit will disappear. You can walk on the switches, or touch them on the Game Pad. Some of them you will not be able to reach with the Game Pad until you move around the area. There are enemies in each area, like bees and a Magikoopa.

After the first two sets of switches, you'll see a warp box. Wall jump over it to find the first Green Star. The warp box will take you to the midpoint. Past the next set of switches are platforms with shoeprints. Stand on them, then jump to spring up. You'll find a Red Coin Ring and a Mystery Box here. In the Mystery Box, use the Fire Flower to destroy the crates. The create in the upper left corner has the second Green Star. At the top, is a set of switches with the Magikoopa. The third Green Star is in the middle of this area, with four switches moving underneath it. Get rid of the Magikoopa to make getting the Green Star easier. Also collect the clocks for extra time. Past the area is a pipe. Let the coin rings line up and fire. This will take you near the flagpole. Hit all the switches here to lower the platform underneath the stamp.

The stamp is of the Super Bell.

Super Mario 3D World: 1-2 -- Koopa Troopa Cave

There's a Koopa near the pipe that goes into the cave. Go through the pipe and you'll see purple brick blocks. There are many Koopas and Goombas here. There are some areas where you can send a shell ricocheting all over to hit blocks and enemies. Be sure not to get hit. Ahead are clouds that infinitely move up and down. The first Green Star is here. Take the clear pipe near the clock to reach the midpoint.

You'll see a Mystery Box nearby. It leads to a room where you have 10 seconds to kill 2 Koopas and collect the second Green Star. Leave the nearby crate intact, as it contains Microgoombas. Keep going and you'll see a long, triple item block. Hit it, then stand on it. Jump to find an invisible triple item block above it, and one more above that. These form stairs to a pipe which leads to the stamp. Drop down and you'll find the third Green Star with a stack of Goombas. Either attack them from below or ground pound them to get it. The pipe nearby leads to the flagpole.

The stamp is a Coin stamp.
