Monster Isle

Monster Isle is an island located near the city of Townsville, and is populated by monsters. Monster Isle is the home of most if not all of the monsters seen in Townsville. If a monster goes to Townsville, fights the Powerpuff Girls and makes it back alive before dark, they are a hero. This is also the home of Steve the monster.

Monster Isle could be a reference to Monster Island which is a fictional location in which giant monsters live on, such as Godzilla.
