New Super Mario Bros. U: Meringue Clouds- Fort -- Slide Lift Tower

In the first room, you'll have to dodge the fireballs of a Fire Bro while getting an Acorn Mushroom. The circling platforms will allow you to reach the pipe to the main level. There are more circling platforms here, as well as more Fire Bros. The first Star Coin is guarded by brick blocks and a Fire Bro. You can fly to break the brick blocks. At the top is a pipe to the midpoint. This part of the level has fire bars. Go past the Fire Bro and go to the right before the arrow sign. Go into the higher alcove for a hidden pipe. This will take you to the second Star Coin. Return to the main level and go directly up for invisible blocks that let you reach a hidden pipe. This leads to a room with challenging platforms. If you make it to the top, you can get the third Star Coin. The pipe at the top takes you to the boss door. There's an invisible item block on the wall with a power-up. Kamek is the boss of this tower. He makes a lot of blocks floating in the air, some of them with enemies. He'll disappear twice, then use his magic to make the blocks disappear, freeing the enemies inside. Climb on the blocks to stomp him. He'll then shoot fireballs which will turn the floor into donut lifts and the cycle repeats itself. This may be a time-consuming battle. Stomp him three times to win. This opens the path to the Ghost House and the Mushroom House.
