A large hariy guy or woman who in there spare time likes to molest small animals and also elephants, they like llamas and like to munch on the nostrils of several kangaroos(mainly austrailan).
On the african grasslands, underneath the ground, hobknockers lurk. They creep until one unsuspecting gazelle or the above said animals are alone, and much like a child predator, SNATCHES THE ANIMAL UP IN ITS MONSTROUS TEETH ! Beware of these odd creepy men, that also like hairy, bingo-winged 50+ ladies.
