Other mistake: When Tinker Bell constructs a boat with the playing cards paddle wheel, she uses a clip and a rope to make sure the paddle wheel doesn't start turning. However the rope would only work at stopping the rotation if the wheel turned backwards. Since it turns forward, the rope shouldn't be able to stop the rotation.

Trivia: A hidden Mickey can be seen when Tinker bell drops her pixie dust on the cotton balls and they float up.
