In every movie, the makers make mistakes, which is hardly surprising in view of the elaborate production. Actually, one could think that this can easily be prevented in cartoons and animated films. After all, those responsible have more control than with live-action movies. But every single shot is full of so many details that it is hardly possible to keep track of all of them. Accordingly, you'll even find some "head-scratchers" in high-class Disney and Pixar movies.
