This location is based on the show Foster's Home for Imaginary Friends. Fuse's interest in imaginary friends has made this area a prime target for Fusions and Fusion Spawns. Fusion Numbuh Five tried to adopt an imaginary friend, while Fusion Bloo tried to infiltrate the house through the plumbing with help from the Toiletnator. While under the control of Fuse, Kevin used a console to transfer Imaginary Energy from the home to Fuse's Lair. Kevin came to his senses later, but the console could not be turned off without harming the imaginary friends.
