Yeti

Yetis are a cryptid of cryptozoology, and have been rarely seen in the Crash Bandicoot games, where it always has the tendancy to eat Crash Bandicoot.

Crash Bandicoot: The Huge Adventure
In almost all 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 enemies to appear in The Huge Adventure without having been in any of the Naughty Dog games.

Crash Tag Team Racing
Yetis are given a disturbing role in CTTR, where they appear in various die-o-ramas, eating Crash.
