Yeti

Yetis are cryptids of cryptozoology, and have been rarely seen in the Crash Bandicoot series, where they always have the tendency to eat Crash Bandicoot.

Crash Bandicoot: The Huge Adventure
In all three of the snow levels, Crash rides Polar while being pursued by a large yeti that is immune to nitro crates, mines, and electric lasers. When Crash escapes, the yeti will be left standing with Polar. This is one of the few creatures to appear in The Huge Adventure without having been in any of the Naughty Dog games.

It is impossible for the yeti to catch Crash and Polar. Therefore, the yeti is there to make the levels feel like chase levels even though there is no need to move at a quick speed. The yeti can also break crates missed by Crash and Polar, which is helpful for obtaining box gems. This only happens, however, when the yeti is still in view on the screen and when he is on the same side of the screen as the crate. The yeti always moves left or right when Crash and Polar do, so if they miss a crate, they should stay on that side until the yeti hits it.

Crash Tag Team Racing
Yetis are given a disturbing role in Crash Tag Team Racing, where they appear in various Die-O-Ramas eating Crash. In this game, they have a more primate-like design.
