The player first needs to press the Direction Switch to the left and ride the moving platforms up, then use a Bob-omb to destroy the Bob-omb Blocks on the left. After pressing the second Direction Switch, the player needs to move right and use the platforms to cross a gap and press a third Direction Switch and a blue Color Switch. Afterwards, the player needs to return to the Direction Switch near the Bob-omb dispenser and press it. Returning back to the platforms on the looped rail, the player is able to ride them and collect the Key, press a yellow Color Switch, and press a Direction Switch. Tossing the Key up and doing a Backflip to collect it again, the player needs to throw the Key through the platforms on the left and climb down the ladder to recollect it. By riding the looping platforms, the player can reach the locked door.
There is a red Color Switch in the level the player does not need to use.
