Wumpa Islands

"The bad... we're going to destroy your precious islands."

- Moritz

Wumpa Islands is a archipelago of three islands, N. Sanity Island, Wumpa Island, and Cortex Island, located at the Australian coast in the Crash Bandicoot series. The Wumpa Islands are the homeworld to Aku Aku and Uka Uka, and they were formerly owned by Doctor Neo Cortex, before his first defeat to Crash. The archipelago is named after the Wumpa Fruit, a type of fruit commonly grown in the area. Wumpa Islands also features two distant islands, Iceberg Lab and the Academy of Evil.

History
Before the Wumpa Islands was a desert archipelago where Aku Aku has always protected eons ago. But with the Neo Cortex's arrival, this archipelago was taken by same with N. Brio where his facilities is built in one of islands for start the Cortex Comandos.

After that Crash Bandicoot was created, this archipelago became independent where which Cortex and his henchmen are defeated by same with Aku Aku tutelage.

Variations
An evil version of N. Sanity Island appears in Crash Twinsanity, in which Crash, Cortex and Nina travel to a mirror universe known as the Tenth Dimension. The Tenth Dimension version of N. Sanity Island is known as Twinsanity Island, and is the exact opposite of the normally-lively N. Sanity Island; the flora is all dead and a black hole-filled purple sky hangs over the entire island. Also notable is the opening on the side of the mountain: the waterfall now flows from a rock shaped like Evil Twins' heads rather than a skull. The island is the former home of Victor and Moritz, who resided in a large stronghold filled with dark, mechanical wonders. Because they were eaten by Evil Crash at the end of Crash Twinsanity, the future of this stronghold is unknown.
