Factual error: When Young Hercules makes the pillars fall in a Domino effect, they go both ways. However, if this were to happen, they would stop the domino effect when they reach the entrance to the market, which doesn't have pillars. The pillars are not in a circle, so there's no way they can both stop at the top of the ring, where the pot seller is. The only way for this to work is if Hercules started the Domino effect at the entrance of the market, with pillars directly across from each other, which he doesn't.
Continuity mistake: When Hercules opens the case, all that falls out are two pots, two bowling pins, a helmet, a sword, and two pairs of armor. A purple cape, two shields, many other pots, a sandal, a trophy, and a white ball with a blue stripe are among many of the additional items that appear out of thin air in the very next shot.
