Other mistake: The fire truck passing by Nani on the way to her destroyed house has the same license plate as the gas truck that Stitch hijacks.
Other mistake: In the beginning of the movie where Baby Jim is talking about Treasure Planet, he crawls under the top sheet of his bed that has been folded half way up the bottom of the bed, and peeks out the bottom. That's fine and all but then his mother straightens out the sheet and covers him up. You then see that the part he just peeked out of was the folded part so he shouldn't have been able to peek out.
