Corrected entry: At the beginning of the movie when Stitch escapes to Earth, the Grand councilwoman is having him tracked and begins to ask questions about the planet, as well as requesting an expert about the planet as she has apparently never heard of it before. Near the end of the movie, in the scene where Stitch has been captured and being taken to the Grand Councilwoman's ship, the Grand Councilwoman comments that Mr. Bubbles "looks familiar", to which he responds that they had met in Roswell. This implies that the Grand Councilwoman had in fact been to Earth before and would have known the answers to the questions she had about Earth earlier in the movie.
Corrected entry: Recall that Lilo's excuse for being late for dance class was that she needed to get a peanut butter sandwich for Pudge the Fish. Now watch the very beginning of the first Hawaii scene when all of the fish swim in front of the screen. One of the fish is Pudge himself, carrying a peanut butter sandwich.
Corrected entry: When Stitch is captured by the Grand Councilwoman and her troops, he is put in restraints. Later, when the Grand Councilwoman releases Stitch, she simply presses a button to open the restraints. Since they're chasing Stitch and treating him as a highly dangerous creature, it makes no sense to put him in such easily opened restraints. (01:13:55 - 01:16:25)
Corrected entry: From the events of the film, Stich is obviously fireproof, so why does he need oven gloves to take the birthday cake out of the oven in the closing sequence?
Corrected entry: When Pleakly and Jumba have captured Stitch, Pleakly calls in to report that their mission is accomplished and adds that they will be waiting for someone to pick them up. Later Jumba shows Nani where their space ship was hidden. Why would they need to be picked up if they had their space ship waiting?
Corrected entry: When Stitch first arrives on earth, he makes his way to a highway. After becoming familiar with rain and encountering a frog, Stitch has three of his four blasters out, one in is top-left hand, and one in each of his right hands. The shot cuts to a very short segment of Stitch staring down the oncoming 18-wheeler, then back to Stitch. When the shot goes back to Stitch, he only has two blasters out, one in each of his right hands. He then proceeds to pull out the two blasters for his left hands, even though in the shot before the cut, he had one of the two already out. (00:24:20)
Corrected entry: Just after Lilo buys Stitch at the animal shelter, there is a scene with Jumba and Pleakly talking outside. The two aliens are talking in relatively loud voices, but notice that Stitch does not react to them talking until Pleakly whispers his line "How good is his hearing?" The writer obviously put that reaction there to answer Pleakly's question, but it makes no logical sense that Stitch would only react to the whisper, and not to any of the rest of the conversation between Jumba and Pleakly. (00:27:30)
Corrected entry: When everybody's surfing, there's a shot of Nani and Lilo surfing, then a shot of David on his board, then a shot of Stitch sitting on the end of a surfboard. Stitch wasn't on either of the other boards, and I'm pretty sure they didn't bring another one. So where did Stitch go during that time?
Corrected entry: At the beginning of the movie, during the opening credits, when Lilo realizes she is late for her hula practice she is racing along the beach pulling her grass skirt and legbands on over her red and yellow swimsuit. She is still wearing this swimsuit as she walks into the school. But when she rejoins the other girls she is wearing the burgundy top that the other girls are wearing. When did she have time to change into this? Even if she did find a place to change, why put on her grass skirt and legbands while running if she knew she would be able to change?
