Well, they may prefer tennis balls to little white marbles, but otherwise, it totally fits! These are not *THE* official Halloween costumes for 2012. I go crazytown for Halloween and always have something made specifically for the girls for their "official" costumes, which aren't quite ready yet. I've had a love affair with hippos for as long as I can remember, if the giant plush hippo in these shots didn't clue you in, so yorkie hippos are pretty much a dream come true!
