Yeti

Yeti are large ape-like beasts native to the world of Anodunos. They appear in Ultima Underworld II.

Description
The Yeti of Anodunos were large violent humanoids of a similar appearance to trolls. Hunting in packs, these hostile creatures assaulted their prey with volleys of high velocity snowballs before beating their enemies at close range.

Trivia

 * Yeti meat was apparently edible to humans, and Mokpo would mention having slain such beasts and partaken of their flesh before.
 * A Yeti is also seen on the box art for Ultima Underworld II. It looks a bit different to the in-game model (which is a re-colored troll), giving a better idea what the species is supposed to actually look like.
