Other mistake: When Cody stole Barney and was running from Abigail and Marcella he hid in the closet, but the girls thought he went to the attic. When he came out of the closet the door made a creaking noise. If the noise was made when he went in, then the girls would have known he was in the closet rather than thinking he went to the attic.
