Other mistake: In the boat with the golden fish, the sign next to the fish says that you must stick your finger in the fish's mouth, then turn around until you "face south". Later, Tony sticks his finger in the fish's mouth and doesn't make any turning motion, yet he still gets the golden touch ability.
Other mistake: After Virginia wins the mirror in the shepherdess competition, she and Tony are in the barn and they hear Sally screaming. Immediately after her screams are heard, a man runs into town and says that she has been murdered. Between the screams and the man announcing the murder, there wasn't enough time for Sally to have screamed at her grandfather, been killed by him, and then been discovered dead.
