A Yeti is a hairy, human-like creature said to live in the mountains in Nepal. Yetis are legendary creatures, but it hasn't been proven either way that they exist or are just a myth.
A zombie, or living dead, is a dead body that can move around because of some form of magic. Zombies are typically very unfriendly and want to go around killing and eating people, particularly their brains. Zombies are frequently seen in horror movies and computer games.
