Continuity mistake: In the scene where the boys are fighting in front of the "Avalanche" ride which Medusa has sped up, Amanda hits the emergency stop button and accidently stops the ride upside down. In the very next shot it shows one of the boys fighting in front of the ride, and the ride is now moving.

Revealing mistake: In all the scenes where Tum Tum kicks the ninjas, you can tell it is a fake leg in the closeups.
Rocky Douglas: It's no good! We need a three-prong outlet.
Question: In real life, do amusement parks actually have a master control room that controls all the rides?
Answer: No they don't, the rides are controlled individually by a ride operator at each ride. This was just made up for the movie.
