Continuity mistake: At one point in 'How Bad Can I Be?', The Once-ler can be seen in two places at once. He leaves and enters onscreen at once.
Suggested correction: The mistake doesn't make it clear where this happens, but I think it's at 00:55:01, where he is on the conveyor belt and stairs simultaneously. However, this is very much not a problem. What about the part at 00:55:18, where there are multiple Once-lers on screen? You wouldn't label that as a mistake, would you? Since it's a highly stylized musical sequence in a stylized animated film, not all of it is supposed to be logical, and this "mistake" might have actually been an intentional choice.
