Trivia: When Jumba's spaceship is struck by lasers, Pleakley can for several frames be seen arguing on the phone with someone. This is recycled animation from when the characters were originally flying a commercial airplane; Pleakley was trying and failing to order luggage sets from the airliner's catalog. (01:09:47)
Continuity mistake: When Lilo tries to teach Stitch to fetch, the wagon changes position between shots.
Continuity mistake: When Nani, Lilo, and the clerk are at the shelter, the posters next to the lift door disappear.
Continuity mistake: At the animal shelter, when the clerk tries to talk Lilo out of adopting Stitch, Nani's arm is very close to Stitch's tummy. A shot later, it's awkwardly twisted around and stretches out from a low place; and yet a shot later, it disappears, only to - drumroll - reappear immediately after.
Continuity mistake: When Stitch leaves Lilo's bedroom, his bed disappears between shots.
Continuity mistake: When Lilo tells Stitch he can leave and that she'll never forget him, a shell on the night table disappears between shots.
Continuity mistake: When Stitch leaves Lilo's bedroom, Lilo's mustard-coloured duvet swaps to green-coloured, plus she disappears from the bed. Sure, her head is off screen, but there's not even the bulk of her body protruding under the covers.
Continuity mistake: When the doll-bomb blasts and Jumba is knocked down, a pink sticky note appears on the fridge.
Continuity mistake: When Stitch finds Lilo's family photo, it lays right next to the top sheets. When Lilo says, "That's us before," the sheets have moved further below.
Continuity mistake: In the dance class scene, the girls slip on the water and fall over. In the next shot, the older girls are suddenly standing a lot further behind them than they were in the previous shot. (00:12:22)
