Disco Puzzle Skip
In the Mermalair Main Chamber, Mermaid Man tasks Patrick with repairing his TV by throwing a melon at 3 buttons. Each button has its own challenge, one of which being a disco floor puzzle. The tiles flash in a pattern that requires Patrick to follow a specific pattern, since Patrick cannot jump while holding the melon.
If Patrick throws the melon on the tiles, the melon does not break. Patrick can jump over the disco floor, onto the melon, and land on the ending platform. The platform deactivates the disco floor, effectively skipping it.
