Jasper usually isn't this big. Usually. For his anthro self to get this big, it probably means that our unlucky squirrel is the last of many. Maybe it was a family reunion and he's coming in late. Maybe he's the chaperone of some unlucky field trip. Or maybe he's just the last morsel in a once crowded park. It looks like everyone else has already been absorbed and turned into raichu padding, so that squirrel will have the tummy all to himself, and it'll be even squishier and cozier than usual. Of course, he'd better enjoy it while he can. He'll be part of that squish before long.
