The Disgustoids disguise themselves as cops so they can walk on the surface, but whilst The Fart wants to follow the duties of a cop, all Festro, Gweelok, Dingle, and Slog want to do is pump up the jams.

The Disgustoids are delighted when Secret Mountain Fort Awesome comes to life and starts wrecking havok on the surface world, but when Fort falls in love with another mountain, Festro tries to break up the relationship, but ends up having to repair his broken heart.

Every time the Disgustoids have a party, Slog turns into "Party Slog" which annoys the bros, but when trouble strikes they need him to do so.
