Potato is so clever. I've seen him do this at least twice. Fuzzy won't let him take the pigloo he wants. So he goes to a different pigloo and rolls around in it wheeking, until Fuzzy comes over to check it it. Potato happily lets him take his place, and then runs over to the pigloo he wanted in the first place.
Usually Fuzzy is too proud to go back and try to take the original pigloo over again.
