Ghost Howl
One of the biggest teases in World of Warcraft, at least as far as low-level Horde is concerned: A beautiful white dire wolf that can't be tamed by hunters and appears to be unusually tough. To be killed on sight by anyone passing through Mulgore, because he does drop a quest item and is really useless for anything else.
If I can't have Ghost Howl for my hunter alt's pet, I will have his pelt for a cape! (Spoken by a druid who later died twice before killing the mutt.)
