The player first has to use a Springboard to reach a platform with a Katakata Yarihō and a Hammer that can be used to defeat it. The Hammer can be tossed up the next platforms to defeat another Katakata Yarihō at the top. Jumping across a gap and then doing a Handstand Double Jump to cross the next gap, the player can press a blue Color Switch. Climbing down and avoiding a Tane Pakkun's attack, the player has to drop down a small gap between the conveyor belt and the platform and then quickly move down a ladder to grab a Hammer, which the player has to use to defeat the two Katakata Yarihōs above them. Once they are defeated, the player needs to grab the Key and toss it up, quickly do a Backflip and grab it again, then toss it into the crevice next to the Tane Pakkun. Before the Key's timer ends, the player needs to drop down and press the red Color Switch, then avoid a Katakata Yarihō to grab the Key again and unlock the door.
- Red: High above the player's starting location.
- Yellow: Next to the blue Color Switch. The player can Handstand Double Jump across the gap to reach it or do a Handstand Jump or Backflip off of the blue platform below.
- Blue: Between the player's starting position and the locked door. The blue Color Switch needs to be active.
