Forks does not really seem like the place for... An escaped exotic pet of some kind? Whatever it is, it's fluffy and and cute seems remarkably clean, with long purple (dyed?) tail and ears. Looks sort of rabbity. It's been hanging out around town for a couple of days, near the school for the most part.
It's very cute, with energetic, puppy-like movements and big round eyes. It's watching everyone at the school most afternoons, almost as if looking for someone.
