The Lake Monsters are a group of monsters that like to party.
Description[]
They appear in "Replaced" when Mordecai and Rigby were throwing a party at the lake in order to protect their jobs by getting Chad and Jeremy fired. When Rigby cranked up the music, the amps fell into the water, resulting in the monsters rising up from the water and wreaking havoc while dancing. A purple monster 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.
