Cortex Tokens (皮質トークン) are collectables scattered around levels in Crash Bandicoot. They are used to access bonus rounds, which are needed to unlock a key, which opens more levels needed to unlock the alternate ending. Cortex tokens are found in Sunset Vista and Jaws of Darkness. The two levels unlocked from the bonus rounds are Whole Hog and Fumbling in the Dark.
