Wumpa Island

Wumpa Island is second island located between N. Sanity Island and Cortex Island, and is the least known island in the series. Not much is known about this island, except that is littered with dated ruins and contains a lava cave below it, where a mine was located in Crash Bandicoot; it is unknown whether this mine still operates today. Also notable is the colossal tree located in the middle in which was the Uka Uka's lair and the tall waterfall that stems from a large tiki head where Ripper Roo was fought in first game.

Wumpa Island was originally to be included in Crash Twinsanity, and would've played two major roles in the game. The first made use of the gigantic tree, where Nina Cortex, Neo Cortex's niece, would use her abilities to swing and climb to the top of the tree (for reasons unknown). The second level would've also involved the ancient temples below, in which the Komodo Brothers built a racetrack, which Crash and Cortex would have to complete in a brakeless vehicle (in a parody of the video game Out Run).
