Crash Bandicoot 2: Cortex Strikes Back

To access a secret area in Level 14: Road To Ruin, go to Level 17: Diggin' It. Towards the end of the level, you'll see a seed-spitting plant on a round platform. Belly-flop the plant to be warped to the secret warp room, where you can access the secret leg of Road to Ruin.

If you skip the first cutscene, you won't have to play the first level, you'll just go straight to the first Warp Room.

In the "Unbearable" level, wait until the second polar bear falls off the bridge then jump down after it to enter a bonus level.
