What happens when you get all the gems in Crash Bandicoot 3?

Collecting all of the Gems unlocks a bonus ending when you finish the game. Found in Deep Trouble via a secret area unlocked by a "!" crate you find at the end of the level. Found in the level Hang 'em High via the secret entrance in Warp Room 6 (requires that you have at least 10 relics obtained to access.)

How do you get all the relics in Crash Bandicoot?

To get a relic, you need to first complete any level. If you replay that level you will see a clock at the start. Walking into this clock will start the time trial which will allow you to get the Relic. For the trophy "Practice Makes Perfect!" you need at least a Gold or better in all of the Time Trials.
