Lake Monsters

The Lake Monsters are a group of monsters that like to party.

Description
They first in Replaced, when Mordecai and Rigby were throwing a party at the lake in order to get Chad and Jeremy fired, and to get their jobs back, when Rigby cranks up the music, the amps fall into the water, and the monsters rose up and danced, and mess up the boats, the purple one didn't like what Jeremy said, so he convinced Mordecai to fight, and all the others as well, but Benson ends it and tells everyone at the party to go home.
