Continuity mistake: When Lilo brings Stitch out to present him to Nani, in the Aloha dog home, the woman grabs Stitch while Nani backs away, holding Lilo. Stitch then walks over to Lilo, with the woman holding onto him, and the wooden door on the counter is wide open. However two shots later you can see in the background that the door is now down and closed. (00:23:35)
Continuity mistake: In the Hula lesson at the beginning of the film the two men in the corner seem to be tapping ipus (gourds hollowed out and used as an implement), but when Lilo makes her comment about Pudge the fish controlling the weather it cuts to the men for a reaction and the one on the right appears to be holding a large red normal shaped ipu. (00:10:30 - 00:12:45)
Continuity mistake: In the scene where Nani is buying Stitch, the woman says "There's a two-dollar licence fee...", on the green wall there is a big large empty space. Then when it cuts to a wideview, after the paper is stamped, a big black telephone is hanging on the prevoiusly bare wall! (00:26:15)
Continuity mistake: After Stitch finds Lilo's photo, he runs across the bed and then Lilo follows him, and you can see the yellow bedsheet covered in stars and moons and planets etc. is pulled up neatly on the bed. However after Stitch messes some stuff around, they return to the bed and now the yellow sheet is mysteriously hanging untidily over the foot of the bed. (00:35:45 - 00:36:15)
Continuity mistake: The door next to the white cabinet/dryer that Lilo hides in is hinged on the frame further away from the cabinet/dryer, which is visible when Nani opens then closes the door to trick Lilo into thinking she has left. However in the scene where Jumba and Pleakley are in the house, going after Stitch, Lilo opens the same door, however it has swapped to being hinged on the frame next to the cabinet/dryer. (00:19:35 - 00:58:45)
Continuity mistake: During the start of the "Bedtime" scene, when Lilo takes Stitch to her room for the first time, notice the nightstand beside Lilo's bed. The top drawer is closed. Stitch jumps up on Lilo's bed and she exclaims "Hey, that's mine." Look at the night stand again, the top drawer is now open.
Continuity mistake: When Nani pays for Stitch at the pound, on the wall there is a fire extinguisher, a sign that reads, "In case of fire", and two other notices, right beside the bulletin board with the "puppy love" poster. These items completely change their positions on the wall, depending on the angle of the shot.
Continuity mistake: In the dance class scene, the blonde girl dancing on the stage (Terissa) has her hair up in two ponytail-style bunches, in red hair ties. When they leave the class, they are still red but when she gets outside and is playing dolls with the other girls, they are now blue coloured hair ties. (00:13:10)
Continuity mistake: At the end of the film, when we see the chase between the two spaceships, the Captain is in a smaller ship that he looks to easily fit in. But when he is on the outside of the ship, the ship doesn't look that much bigger. The red ship was miles bigger than the yellow one and the Captain fits in the yellow one easily. The sizing is completely out.
