Usually a blob of pure pudge. Jiggle a LOT when they walk. Really dumb, might accidentally sit on you. If you don't move, they usually don't notice you. They accidentally moon people a lot when they try and squeeze their huge amount of flabby blubber into skinny jeans. Usually have absolutely NO clue what their toes look like. Totally scared of high pitched noises.
