Continuity mistake: A couple of scenes after the baker's wife ripped off most of Rapunzel's hair, it has grown back to full length so that the prince can climb up to the tower on it.
Continuity mistake: When Larry and Nick Daley first enter the British Museum, Nick takes his beanie off twice, in consecutive shots.
Continuity mistake: Just before seeing Principle Celestia, and they are walking down the hallway, the cutie mark on Sunset's shirt disappears.
Character mistake: When Mr. Rogue is spinning the globe to assign countries to the students he spins for Albert Morio, and he puts his finger just west of North America and says "Lebanon." Lebanon is in Asia, slightly northeast of Egypt and we can see Egypt on the globe on the other side of where his finger is at. He's nowhere near Lebanon.
Continuity mistake: During the "Perfect Puppy" silly song, Bob places a newspaper he had been reading on the couch beside him when Larry starts singing. When Bob shows Larry the picture of the dalmatian, the newspaper has vanished. When the shot cuts back to Bob, the newspaper has returned. (00:16:55)
Continuity mistake: The dog the boys were trying to catch was facing the fence with his nose very close to it. After one of the boys threw a blanket (or piece of material) over the dog, the dog was facing them instead of the fence. Also, the dog was not as close to the fence and the background didn't appear to be the same. (00:06:07)
