Several of the Crash Bandicoot games have levels with penguins as the enemies. It is almost sad to kill them that sometimes I just avoid them instead of killing them like I do other enemies. It is just a game, though, so I do not feel that bad if I do it. In most games the penguin characters look most like Adelie Penguins, although the one in The Wrath of Cortex has hair kind of like a Macaroni Penguin (this is the one pictured in my screenshot below).
There first appearance is in the Snow Go, Snow Biz, and Cold Hard Crash levels of
