Turtle Woods

Turtle Woods is the first level in Crash Bandicoot 2: Cortex Strikes Back. While on the surface it appears to be nothing more than a basic introductory level, clever players will find several intriguing secrets along the way. The first Bonus Round of Crash 2 appears here, under a breakaway floor. Earlier in the level, a stone face appears on the ground - belly flopping it will reveal another secret area, considerably more difficult than the rest of the level, that introduces Crash to the brand-new Nitro Crates and Nitro Switch Crate, and requires several tricky jumps from oversized ostriches to fully complete. The Blue Gem is also found in this stage, counter-intuitively requiring the player to clear the stage with zero crates broken to obtain.

Armadillo
A simple armadillo with a blue back and white bottom. Can be defeated with any attack

Spike Turtle
Partially robotic turtles with spikes around its sides. Can be neutralised by jumping on it and using its shell to bounce on it, or can be removed by spinning after jumping.

Vulture
Only found in the secret stage, is also partially robotic. Can be killed by jumping on it or avoided by jumping over it.

Ostrich
Provided you act quickly, they are more of a help than a hindrance. If you jump onto them quickly from the top while they're putting their head in the ground, you can access the higher boxes you need to get the clear gem. Due to their massive size they can't be defeated, but the ostriches are harmless anyway.

Trivia

 * This level's name is a clever pun on the name of real-world golf athlete Tiger Woods, who was just coming to national prominence when this game was released. Tiger Woods would continue to have a squeaky-clean untarnished record throughout the rest of his career, just as the Crash games would apparently maintain the same high level of quality forever. "Turtle", obviously, refers to the numerous turtle enemies in the level, boringly enough.
 * The game hints at the existence of the Blue Gem in this stage by rendering the crate tally at the end of the stage as "(number of crates obtained)/0" on each playthrough of the level after the player obtains the Clear Gem. However, mathematically, zero cannot be the denominator in a fraction, a rare continuity error on the part of Naughty Dog. Most nerdy fans hope this is fixed when this game is remade.
 * Some fans find it troubling that this stage's secret route continues to perpetuate the myth that ostriches bury their heads in the sand. In reality, this is something that they just do not do, as obviously this would cause them to suffocate. Nonetheless, society decides it's best to ignore this truth, instead opting to hide from it, metaphorically burying their heads in the sand, like ostriches do.
