Pecola in a Yacht of Trouble (Japanese: ヨットレースは大騒ぎ)

It's Dr. Chu vs. Pecolius in Cube Town's first Yacht Race, with Little Chu as Dr. Chu's first mate and Pecola helping out Pecolius! The boys get swept up in the competition, so much so that they lose focus on what's really important, having fun and respecting your friends.
