Gone Tomorrow

Gone Tomorrow is the twenty-first level in Crash Bandicoot 3: Warped. It is set in a futuristic place like Future Frenzy. There's also a new enemy; a big robot which shoots four missiles (three in the NTSC version), then turns around exposing its weakness being a green target, giving Crash the time to shoot it with the Fruit Bazooka or spinning it.

This level has 87 boxes and 2 clear gems. To get the gems, you must have the green gem from the Aladdin-themed level under the name Flaming Passion and enter the secret area, which gives you the secret gem. It then teleports you to the start of the level. This is important because the secret path has many crates and a switch in it that activates even more crates. After that, you just have to complete the level normally to get the box gem.

Trivia

 * The name is a pun on the idiom "Here today, gone tomorrow."
