Super Mario 3D World: 3- Castle -- The Bullet Bill Express

This is an automatically scrolling level. At first, you're on the station platform with the train moving. Hit the item blocks for a cannon box, then quickly get on the train and go to the back for the first Green Star. Bullet Bills will be firing at you. You must get on the train or you'll soon run out of platform and fall. Once on board, move towards the front of the train. There are spinning flies near the item blocks, which have Super Leaves for Tanooki Suits. A train will appear in the background and fire Cat Bullet Bills that will home in on your location. Ahead is the second Green Star in a stack of Goombas. Nearby is an invisible block with a Mega Mushroom. Use it, which helps with the Cat Banzai Bills, but do not destroy the green pipe ahead. Take the green pipe to the train in the background.

On the back train, the level will continue to scroll. You'll find a few crates. Break them to free Captain Toad to get the third Green Star. Over the engine is a warp block back to the main train. There are Fire Bros near the engine. Drop down to enter the engine for the stamp. The pipe on the engine will take you to Pom Pom. She has a ninja star this time. She'll split into three and attack. Hit the one with the pink ninja star and she'll split into four, then five. Once you defeat her, the warp box to the flagpole and the blue Sprixie Princess will appear. Once you free her, she'll use a hammer to create a clear pipe.

The stamp is of Pom Pom. The Sprixie House here has the stamp of the yellow Sprixie Princess.

Super Mario 3D World: 3-7 -- Switchboard Falls

The arrow platforms on rails make a reappearance. Stand on one side of the platform to make it go that way. Once you stand on the platform, it will move until it runs out of track. Either the end of the track will stop it or it will fall off. There are Fizzlits here, purple enemies that flatten out into electrifying puddles. Go down the rails, then go left up a hill. There's an invisible 1-up in the center. Drop down and you'll find an invisible Starman on the wall. Go to the right and you'll see a giant red ! Block over the rails. Hit it to change the track, then go in the opposite direction. There are fuzzy caterpillars on the track, so jump over them, or beat them with the Starman. Hit the other ! Block to change the track again, which makes the switchboard go down hill. Jump at the alcove and go into the pipe.

You'll land on a donut lift, which will fall. Follow the trail of coins to the first Green Star over the water. Return to the main area and drop down to the midpoint. Here, the Fizzlits will start moving around, so be careful. There are Red Coins to collect if you like. Take a switchboard to the waterfall ahead and jump behind the waterfall where the bees are. Run to the right, then drop down through the coin rings. You'll land on another switchboard. It will start moving from under a ledge, so when you can, make the switchboard go in the opposite direction and duck. This will take you to the second Green Star. Go forward and you'll find fuzzy caterpillars and ! Blocks on the track. Be sure to hit the ! Blocks. The switchboard will drop and there will be more caterpillars. Go up to find the third Green Star. Go back, then transfer to the switchboard below to reach the stamp. Keep going and you'll reach the swtichboards in front of the flag.

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.

The pipe will take you to the midpoint. Get back in the water and swim towards the ceiling to find a hidden room with the stamp and a Cannon Box.
