Go to the part where Ursala's transforming Ariel into an erotic human. When Ariel receives her legs she's inside a bubble. The bubble breaks, and there's probably 50 bubbles surrounding the naked woman. It cuts the the shot of Ariel trying to swim, and then it cuts back to a further away shot, and look around. Where'd all those bubbles go? 50 bubbles couldn't have dissapeared that quickly. But, even with this blooper, this is still the best scene of the whole movie.
