Kooey Kooey Kooey is an island in the South Pacific. The island was revealed to be a sentient creature that would occasionally decide to uproot itself and wander about on its own.
Kooey Kooey Kooey was also used as a proving ground and secret lair for the otherworldly villains known as the Extremists. It was here that Extremists member Dreamslayer took mental possession of JLI liaison Maxwell Lord and attempted to reforge his former team. Dreamslayer fought in a psychic dual with the super-hero Silver Sorceress. Though the Sorceress proved victorious, she paid the ultimate price. Her allies in Justice League Europe as well as Blue Jay buried her remains on Kooey Kooey Kooey.
A short time later, Kooey Kooey Kooey was seemingly destroyed by a tidal wave sent by extradimensional invaders.
