Layout
As its name states, this level is mainly set on halls surrounded by rainbow walls, as well as colorful wooden blocks. The first part is a vertical way with Bill Blasters on each side, and the players must get to the top using two Switchback Platforms. Next, there is a horizontal path with some pits and some small-sized platforms with a Green Ring at one point, followed by the final area, where a Blue Ring, a couple of Waddlewings and a few Bill Blasters appear. At the end of this area, there is the Goal Pole.

Star Coins

 * Star Coin 1: The first Star Coin is floating above the Bill Blaster path.
 * Star Coin 2: Near the start of the rainbow line in the second area, there is a secret pipe behind the blocks that leads to a bonus area, where the Star Coin can be obtained by using the Switchboard Platform and the POW Block.
 * Star Coin 3: In the second vertical area, the player must activate the Blue Ring to turn the three subsequently found Brick Blocks into coins, opening a passage to the third Star Coin.
