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.
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.
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: 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.
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.
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.
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: During the "bedtime" scene, Stitch finds a picture of Lilo's family. Look toward the back of the room to the left of Lilo as she scolds Stitch by saying, "Be careful of that. You don't touch this. Don't ever touch it." You can see a lei hanging on the outer corner of a painting easel. Stitch then jumps down to the floor and attacks Lilo's doll, she scolds him and Stitch rolls up to the easel and proceeds to destroy the picture on it. You can see that the lei is no longer on the easel but is now hanging on the window behind Lilo, from which she removes it and places it around his neck.
