North Sanity Island, also known as N. Sanity Island and Jungle Island, is the first and most recurring of the three islands, being the home of Crash Bandicoot and his companions (until Crash Of The Titans). Much of the island is occupied by a large mountain located in the center. On the side of the mountain is a skull-shaped opening that expels a waterfall from its mouth. The resulting river passes through N. Sanity Beach, where Crash's very first adventure began. Before the overthrow of Cortex, the island was largely inhabited by the native tribesmen (led by Papu Papu), who would capture and/or eat anything that sneaked into their territory.
