New Super Luigi U: Layer-Cake Desert- Fort -- Wind-Up Tower

This Fort has gears to spin that temporarily move stones into place so you can climb up. This is where Luigi's lack of traction can be a huge issue. You don't have a lot of time to climb back up if you fall, but keep trying. Spin the first gear and jump up before the stones come together. The stones form stairs. The first Star Coin is behind the vertically-moving stone. Jump quickly to get it before it is covered up. Keep climbing past the Dry Bones and get a powerup. Above is a second gear. To the right of the gear is an invisible block with a 1-up. Spin the gear, but do not move the stones all the way. This is where the platforming gets a little tricky. Climb up and get the second Star Coin. When you reach the top, go right, then up for the third gear. The stones will separate, but only briefly. You must move quickly to get out of there alive. Drop back down if you can to spin the gear again if you need to. There's an 8-bit Luigi here, and the third Star Coin is revealed towards the top. After surviving that, go through the boss door. Kamek will power up Boom Boom, making him spin. Defeat him and a tornado will surround Peach's Castle.
