This glitch works on all versions of the game. At the start of the boss, when Uka Uka jumps down, throw Cortex onto the platform he jumped from. Cortex will teleport back to the edge of the arena while doing this make sure to avoid Uka Uka's attacks. Then jump on Cortex's head and Crash can escape from Uka Uka. When doing this, make sure to stand away from the edge to make sure Uka Uka doesn't hit Crash with his snow ball throwing attack.
- Returning to the boss fight just after losing a life can trigger a huge glitch where during the cutscene just before the boss fight, another Uka Uka will be visible in the background and as a consequence, the game will most likely lock-up afterwards.
