Pete breaks the club's air-conditioner on a very hot day and the only guest left is Supreme Nether Underlord - Hades. Now, Mickey and the gang must stop Pete from driving the Supreme Nether Underlord away and shutting down the club. Pete eventually succeeds in driving away Hades by flooding the club, but this results in The Little Mermaid characters returning.
