New Super Luigi U: Acorn Plains- Castle -- Lemmy's Lights-Out Castle

The castle is dark, but has overhead lights that swing. Some of them move with the pendulums in the castle. The first Star Coin is over a high pendulum that swings over another. There's a Red Coin Ring that makes Red Coins appear over the pendulums swinging over the gap. Collecting them all will give you a 1-up or an Acorn Mushroom. You'll need it to reach the second Star Coin, which is below a pendulum. Drop down to get it, then boost to safety. Over solid ground are a set of three brick blocks. The middle one contains a P-Switch. This will turn the coins into brick blocks so you can safely travel over the Nippers. Drop down into the gap between two sets of Nippers for a pipe. This leads to the third Star Coin, over a pendulum. The boss door is ahead. There's an 8-bit Luigi on the right wall. Going through the boss door will add 100 seconds to your time. Launch from the cannon to the Airship. Lemmy stands on a bouncy ball and tosses bombs. Stomp him three times to defeat him. You'll open the path to Layer-Cake Desert. You'll also get a message saying that you've collected all the Star Coins, which should mean something good. Save your game.

New Super Luigi U: Acorn Plains-5 -- Piranha Gardens

Aside from Piranha Plants, there are Hammer Bros in this level. The first Star Coin is under the ledge with the Red Coin Ring. The second Star Coin is near the second Hammer Bro. There's a 1-up in the second brick block from the left on the top level of brick blocks where the second Hammer Bro is. Keep going and you'll see a giant Piranha Plant on the rock above. Enter the hidden area from the left side of the rock for the third Star Coin. Keep going to reach the flag.

New Super Luigi U: Acorn Plains- 4 -- Piranha Heights

Before entering the level, have Pink Baby Yoshi follow you. This level has pipes and moving mushroom platforms with Piranha Plants. The first Star Coin is above and to the right of the first set of pipes. To the right is a long platform above a mushroom. You'll find an Acorn Mushroom over the mushroom. The second Star Coin is above the second set of pipes. There will be two pipes near the top that have coins between them. Fly between those pipes to reach a pipe to an 8-bit Luigi and the third Star Coin. The pipe on the right will take you to the flagpole.

New Super Luigi U: Acorn Plains-3 -- Rolling Yoshi Hills

There are rolling hills here, which affect your speed. Monty Moles will pop out of the rocks, so keep an eye out for them. Throw a Koopa shell to the right, under a ledge, to get the first Star Coin. Nearby, you'll find a couple of item blocks, one with a Yoshi in it. To the right are hidden alcoves with coins. There's a low platform with lots of Piranha Plants. Use a shell on the other side of the gap to clear them out so you can get the second Star Coin. Up ahead are a couple of POW Blocks so you can get the coins in the sky. The third Star Coin is just in front of the flagpole. Use Yoshi or a POW Block to get it.

New Super Luigi U: Acorn Plains- Fort -- Flame-Gear Tower

This fort features gears and jet engines. Go over the first gear, avoiding the engines, then when the flames coming down on the right side stop, jump for the first Star Coin, then wall jump to safety. There are flames below the Star Coin. Just above it are a cluster of four engines spewing flames to the left. The second Star Coin is in the flames, so time your jump to get it. Keep climbing up and you'll see a Dry Bones on the right side. There are two engines above it. Between them are two levels of invisible blocks. This will allow you to reach the third Star Coin between the flames. At the top, there are a lot of Dry Bones by the boss door. Going through the boss door will give you 100 extra seconds so you can defeat the boss. Boom Boom is the boss again. Stomp him three times to win. After you win, you can save the game. The path ahead splits to Acorn Plains-3 and -4.

New Super Luigi U: Acorn Plains- Cheep-Cheep -- Cheep Chomp Chase

This water level has a lot of pipes. There is an invisible block over the red pipe with a Starman. Get it and go through the red pipe. There are lots of Cheep-Cheep as well as Big Bertha, the man-eating fish. Swim to the left, between the pipes, for the first Star Coin. The big item block below has another Starman. There's a Red Coin Ring between some pipes. Follow the coins, then swim up, over where the last Red Coin is and the second Star Coin will drop down from the gap in the pipes. Swim up through the gap to reach a new area with the third Star Coin. Keep going to the right, over the pipes and you'll see some rotating pipes. This will take you to the flagpole. This will open the path to Soda Jungle-1.

New Super Luigi U: Acorn Plains-2 -- Crooked Cavern

It's time to go underground. Drop down to the level of the Piranha Plants and walk to the left past them. You'll find a hidden area with the first Star Coin. Go through the middle pipe where there's moving crystal. Wall jump between the two left pipes to find a hidden block with a Starman. Go to the right and wait so you can safely jump to the next crystal. You'll see a couple of Koopas. Stomp one and pick up it's shell and throw it into the brick blocks to get the second Star Coin. Walk right, then drop down to a lower crystal when the coins between the crystals are visible. This way, you'll land on the brick blocks below. Jump onto the higher brick blocks, then go right, where you'll find some Koopas and Piranha Plants. To the right is a pipe with an arrow. This will take you to the flagpole. There's a hidden 8-bit Luigi in the brick block stairs. This will open the path to Acorn Plains- Fort.

Get an Acorn Mushroom to get the third Star Coin. You'll have to pick it up elsewhere; you can't find them in this level. Jump from the platform below the pipe to the flagpole and glide to the right. The third Star Coin is here. A little to the left of the third Star Coin are some hidden brick blocks in the ground. Pound them to drop down, then walk to the right, where there's a yellow pipe to the red goal. This opens the path to Acorn Plains- Cheep Cheep.

New Super Luigi U: Acorn Plains-1 -- Waddlewing Warning!

It's time for Luigi's first solo platforming mission! There are lots of Waddlewings here, the flying squirrels. Each of them carries an Acorn Mushroom, so there are plenty of opportunities to power up. At the start, there's an 8-bit Luigi with a sort of "title screen". There are hidden 8-bit Luigis throughout the game. As with all levels, you have only 100 seconds to complete the level, not leaving a lot of time to explore. The first brick block has a 1-up in it. The first Star Coin is nearby. Follow the first trail of coins up by boosting as Flying Squirrel Luigi to get it. There are a few Piranha Plants in lower parts of the level. The second Star Coin is below one of the moving pieces of land. Glide from the right to get it, then boost to safety. Follow another trail of coins and glide past some flying Waddlewings, then boost to get the third Star Coin and reach the flag. This will open the path to Acorn Plains-2.

New Super Mario Bros. U: Acorn Plains- Blooper -- Blooper's Secret Lair

This is a secret level, which is technically part of the same world as the level with the secret exit, but is located in part of a different world. This is part of the beach world of Sparkling Waters. The secret levels do not have midpoints. We take a pipe underwater. This level is filled with pipes, some with Bloopers hiding in them and some with currents. Some of the pipes with currents rotate around. Get the Fire Flower because you'll need it to deal with the several Bloopers in the area. Past the three pipes with Bloopers in them are two pipes with currents coming down from the ceiling. The first Star Coin is between them. Align yourself between the two pipes and swim up. The yellow pipe below has a current that may help you reach it. Soon after you'll see a set of rotating pipes to the left of the second Star Coin. Swim directly under the red pipe to the left of the Star Coin to reach it. Keep going to the right and you'll see a Red Coin Ring. The currents from the pipes along the way may help or hinder you in getting them. At the end of the area is a green pipe in the ceiling and a red pipe below with a Blooper. Go through the green pipe. This leads to another underwater area that is vertical. There are two Bloopers in the pipes to your left and right. There's a set of rotating pipes with currents immediately above you. Stay to the left. On the left wall are three green pipes stacked on top of one another. The lower one has a current. Take the middle pipe. Drop down for the third Star Coin and return the way you came before the two Blooper Nannies make life difficult. Swim to the top of the level, while dealing with a Blooper and lots of pipes with currents. The pipe at the top leads to the flagpole. This opens the path to a new world, Soda Jungle. We can save our game now. We get a message saying, "You got all the Star Coins in Acorn Plains! That's gotta mean something good, right?" We shall see when we collect more Star Coins.

New Super Mario Bros. U: Acorn Plains- Castle -- Lemmy's Swingback Castle

As the name suggests, there are lots of swings in this castle. There's also lots of lava. Get the Acorn Mushroom, then the first Star Coin by transferring swings. Avoid the Podoboos and use the tiered swing to reach the higher swing to the right. When you reach solid footing, you'll find the midpoint nearby. The floor will end and you'll have to deal with more lava. Use the Acorn Mushroom to glide for the second Star Coin. Afterwards is a Red Coin Ring. The swings will be much closer to the lava and some will go into the lava, so jump when they do. There will be more swings, then a pipe in the lava. Carefully drop down to it. It leads to another room with lava with a swing that goes into the lava. The third Star Coin is above the swing, so get on the swing, then jump to get the Star Coin when it goes into the lava, then land when the swing is out of the lava. Return to the main level. You'll be near the boss door. There's a Fire Flower in an invisible block on the right wall. The door leads to an open part of the castle where we can see Lemmy's Airship flying by. At the top of the stairs is a cannon, which will blast you to the Airship. We land inside the Airship where Lemmy is. Lemmy stands on a bouncy ball and throws bombs. Avoid the bombs and stomp Lemmy. He'll go spinning around in his shell, then stop, and stand on another bouncy ball and start throwing bombs again. The best way to deal with the Koopalings is to stomp them as soon as they get out their shell cycle. Three stomps are all you need to defeat him. We win and Mario stomps around on Lemmy's Airship, which flies off and crashes somewhere. We save the game and head to the next area, Layer Cake Desert.

New Super Mario Bros. U: Acorn Plains-5 -- Rise of the Piranha Plants

This area has lots of Giant Piranhas. The Fire Flower is very helpful here. There are coins under the area near the rising Piranha. The first Star Coin floats over a giant Piranha Plant. Baby Yoshi can help you get it. There's a Hammer Bro in front of the midpoint. The path ahead is slanted and has more giant Piranhas. After them is another Hammer Bro. There's a pipe blocked by a Piranha Plant. Defeat the Piranha, then go through the pipe to an area with the second Star Coin over a couple of giant Piranha Plants. Return to the main level and avoid the Piranha Plants on the ceiling. The third Star Coin is guarded by a Hammer Bro. There is slanted land to the flagpole. This opens the path to the castle and a Mushroom House. Time your jump over the Piranha Plant in the pipe to avoid dealing with it, or backtrack and go past Acorn Plains-4.

New Super Mario Bros. U: Acorn Plains-4 -- Mushroom Heights

It's a mushroom platforming level. Some of the mushrooms move. The clouds overhead conceal coins. Pink Baby Yoshi is a great help here. There are strange-looking Goombas walking on the mushrooms, but they don't walk off. Use Baby Yoshi to reach the first Star Coin over the blue mushroom. The midpoint is on a different blue mushroom. The second Star Coin is under a blue mushroom, but it's over the void. Use Baby Yoshi to get it, repeatedly hitting [ZR], until you're over a mushroom to stand on. Go down the green pipe between the four pink mushrooms that expand and contract. It will take you an area with moving mushrooms and some Goombas. Kill the Goombas first, then activate the Green Coin Ring. This is a new ring, that makes green coins appear in triplets. Get all three before they soon disappear to make another triplet appear. All told, five sets of three green coins will appear. Collect all fifteen green coins to get a powerup. Return to the main level and you'll find the third Star Coin under a tilting green mushroom between two giant Piranhas. Baby Yoshi can't eat giant enemies. It may take a few attempts to get it. After that is the flagpole. This opens the path to the castle.

New Super Mario Bros. U: Acorn Plains-3 -- Yoshi Hill

This level has lots of rolling hills and Monty Moles jumping out of the rocks. There's a Yoshi in an item block. Use Yoshi to flutter jump from the hill for the first Star Coin. There's lots of fruit in the level for Yoshi to eat. If he eats five fruits, he'll lay an egg with a powerup. If Yoshi eats the powerup, nothing will happen, so just run into it to get it. There are some brick blocks past the first pipe that lead underground to an invisible area. Run underground to the red pipe, which leads to the second Star Coin. It's over the yellow pipes with Piranha Plants and it moves. Once you return to the main level, there will be a stretch of land where eight Monty Moles will appear at once. It's just in front of the midpoint. Coins will appear out of the mole holes if you wait a short while. The next area has raised land with gaps in between to the void. Between two pieces of land with Monty Moles, which are between two yellow platforms, is a red pipe in the gap. This will take you to the third Star Coin. Run and jump to get it. Afterwards are Fire Piranhas and rolling hills leading to the flagpole. This opens the path to Acorn Plains-4 and Acorn Plains 5.

On the path to Acorn Plains-4 is a pink Baby Yoshi. It says it will follow us because it looks like we know where to find food. We take it into Acorn Plains-3 and it will eat small enemies, like Piranha Plants and Monty Moles, but won't touch the fruit. It also sings when you hold it. Press [ZR] to make it balloon so you can reach new areas. We reach the flagpole with it and Toad thanks us for the help and gives us a Super Mushroom. Pink Baby Yoshi still follows us around.

New Super Mario Bros. U: Acorn Plains- Fort -- Crushing Cogs Tower

This fort is filled with spinning cogs to help you reach new heights, as well as possibly crush you. Climb up the first set of cogs and get the Ice Flower from the item block. There are Dry Bones in here, so use the Ice Flower to get rid of them. Wall jump up the right side of the fort to reach the first Star Coin. There's a moving stone above it that will block your access to the Star Coin, but it won't hurt you. Take the platform up, climb past some cogs, and go left for the second Star Coin. There's a Red Coin Ring over a cog. Soon after, you'll reach the midpoint. There's a set of three cogs above, which can crush you. The one on the right will crush you, so jump off it immediately. Jump from the cog to the left over to a ledge on the right wall. Jump up from there for an invisible area to the right, with a pipe cannon that takes you to the third Star Coin. You'll soon reach the boss door. The boss of this fort is Boom Boom. He runs around flailing his arms and bounces off the walls. Stomp him three times for victory. Mario kicks him out of the fort and the path to Acorn Plains-3 opens up. We can now save our game.

New Super Mario Bros. U: Acorn Plains-2 -- Tilted Tunnel

It's time to go underground. There's a Fire Flower in the item block above the Piranha Plants. They can't hurt you. Take the pipe underground, where there's lots of moving crystals. The crystal platforms may move when you step on them. Take the floating platform moving left and right to a crystal slide with coins. Jump at the end of the slide for the first Star Coin. Soon after is the midpoint. There are two brick blocks next to a Piranha Plant in a pipe. Use a Koopa shell to hit the upper brick block to make a vine appear. It will take you to a pipe cannon, which will fire you to the second Star Coin. Nearby is an area with lots of pipes. Take the lower, left green pipe down to an area with Buzzy Beetles and a POW Block. The POW Block will make coins rain down from above. Once you return to the main level, go to the right and you'll see a Red Coin Ring over the pink crystal. Afterwards, there will be crystal with a sign pointing down. Pound that crystal to move it out of the way so you can access the pipe below. The third Star Coin is at the bottom of a crystal slide. Once you get it, the crystal will move. Return through the same pipe. The pipe to the flagpole is not too far away. This opens the path to the Mushroom House and the Fort.

After completing the level, we see that the flags on Peach's Castle now bear Bowser's emblem.

If we return to the level and go over the rocks onto the ceiling in the area of the Red Coin Ring, there's an area with coins above. Before you go too far, jump again to access a higher level. Run over the pipe to the flag and drop down on the right side to find a different pipe. This will lead to the Red Goal. This opens the path to Acorn Plains-Blooper.

New Super Mario Bros. U: Acorn Plains-1 -- Acorn Plains Way

We find ourselves in Acorn Plains, a peaceful, green World 1. The acorns we saw in the introduction are Acorn Mushrooms, which will turn Mario into Flying Squirrel Mario, allowing him to glide down to the ground and cling to walls. We can get an extra height boost when jumping by hitting the [ZR] button. The first Acorn Mushroom we can get is in the clutches of a flying squirrel enemy. Glide from the first high ledge to reach the first Star Coin. Go down the next green pipe for the second Star Coin. Return to the main level and you'll see a rising piece of land. To the lower right of it is a hidden area with coins. Nearby is the midpoint. Pound the brick blocks in the ground under the sign with the arrow for more coins. Soon after, you'll see a Piranha Plant, as well as a Red Coin Ring. Use [ZR] to get a boost to a platform overhead with a pipe. The pipe will take you to a free-fall area with a trail of coins. Follow the coins (or stay in the center if you don't have an Acorn Mushroom) for the third Star Coin. Return to the main area and it's a short distance to the flagpole.
