Pukupuku Kai

Pukupuku Kai (プクプク海, or "Cheep-Cheep Waters") is the sixth stage found in Mario & Wario. It is an underwater place that has many Switch Block puzzles. Two Cheep-Cheep are seen in the background of the stage, with a third in the school not like the others. During the stage intro, Wario puts a jellyfish on the character's head.

LEVEL6-1
This course is a primer to the Switch Blocks, which turn all the blocks of its type on or off. The fall from the top right to Luigi is designed to teach the player to activate them at the right time.

LEVEL6-2
This course introduces Unibō, which are urchin-like creatures. Touching them means the loss of a life, so Wanda must make her character dodge them while working with tiny Switch Blocks and elevators. Luigi must be reached via dropping through the top right.

LEVEL6-3
This course has a Tsubōn guarding passage to the left, but Wanda can simply flick the Switch Block it's clinging on to defeat it. After that, the player must handle alternating Switch Blocks and Unibō patrols. Luigi is in the top right.

LEVEL6-4
The character begins this course on the top left, and must navigate their way through several Unibō and elevators. Luigi to the left of the bottom floor, but getting the Stars and reaching Coin Blocks may prove to be less simple.

LEVEL6-5
This course has several horizontal rows of Switch Blocks with vertically-moving Unibō. The course is thus fairly basic, but dropping to the wrong area may make the player unable to collect some Stars.

LEVEL6-6
The first half is a descent with a sort of zig-zag with both horizontal and vertical Unibō, as well as some tiny Rock Blocks. The second half on the right is an ascent up some elevators with carefully-placed tiny Rock and Jump Blocks, and horizontal Unibō.

LEVEL6-7
The beginning is similar to LEVEL6-4, but with trickier spots concerning elevators, Rock Blocks and Unibō. The middle section is also mandatory, and there are even tighter spaces if the player isn't careful. Luigi is in the bottom right.

LEVEL6-8
This course is mostly a simply path from the top right to the top left, with more alternating Switch Blocks and elevators. However, there are also many spikes.

LEVEL6-9
This course is a sort of spiral structure from outside to inside with Unibō and tiny Switch and Jump Blocks. It is easy for the player to get trapped with a Unibō with this setup. The character is safe once the character is on the elevator to Luigi and a Star.

LEVEL6-10
This course has a deceptively simple path to Luigi from the bottom right tiny Jump Block, provided the player does not get overwhelmed by the new Switch Blocks that hold their character in place.
