Continuity mistake: When TJ's friends climb on the jungle gym to try and take TJ's place, we see that Gretchen is the last one up and there is no-one on the bars behind her. But in the next long shot, Mikey is right behind her. Then when it shows a close-up of them, Mikey is gone again; then he reappears a moment later.
Continuity mistake: In the time before King Bob tells his story about being the Prankster Prince, no one is on the jungle gym except TJ and his friends. But after Bob finishes, around 20 kids are on the jungle gym, plus TJ and co. There was not enough time for ALL those kids to get on top of the jungle gym from the time King Bob started his story to the time he finished.
