Continuity mistake: In one shot of Lilo in the spaceship near the end of the movie, her family picture disappears.
Continuity mistake: In the beginning of the movie, a few seconds after Lilo attacks Myrtle, all the girls, including Myrtle, gather behind the director. Myrtle's bracelet of leaves is still on. Then when it cuts to her, Myrtle says, "Ew, she bit me." and the bracelet is gone. (00:13:10)
Continuity mistake: When Nani discovers the large pot overheating on the stove, moments later it is a small, flat pan. (00:11:05)
Continuity mistake: When Nani brings Mr. Bubbles into her home, she spots the paper on the fridge that says "Home Alone," and she runs over to hide it. In this shot you can see that the top of the fridge is empty. Then in the next shot a green towel is hanging down off the top. (00:10:55)
Continuity mistake: When Lilo shows Stitch her bedroom for the first time, we see a hula girl lamp on her bedside table. Then when Stitch is on the floor across the room, building "San Fransisco" out of books and toys he reaches over and drags the lamp toward him as if it had been on the floor beside him. Moments later the lamp is back on the table, and the mess is gone.
Continuity mistake: When Lilo is running up the beach in the initial shot of her, it then cuts and Lilo stops, takes out a camera, and takes a photo of a man. However the bushes/branches behind Lilo disappear and reappear a few times between shots. (00:10:40)
Continuity mistake: When Nani, Stitch and Lilo are at home passing from stairs to entrance, you can see the light switch close to the book shelf. When they reach the entrance, the light switch has gone.
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.
Continuity mistake: Lilo takes the headdress off a redhead girl during a fight at the dance practice; a few seconds later, none of the girls have their headdresses on. (00:12:45)
Continuity mistake: When Mr. Bubbles visits Nani's house for the second time, he first meets Stitch. Stitch, throws the book he's holding at Mr. Bubbles' head. Nani then grabs Stitch up in her arms and proceeds to apologize to Mr. Bubbles. Before she grabs him, Stitch was standing upright, just in front of and to the left of Nani. However, Nani reaches right in front of herself to grab Stitch. Nowhere does it show that Stitch moved. Also, when Nani picks Stitch up, she has him in her arms upside down, facing Mr. Bubbles. Since he was standing upright, facing Bubbles when Nani grabbed him, Stitch would not have ended up in that position.
Continuity mistake: When Nani is first seen in her room, we see an alarm clock reading 7:15 on her bed frame. A couple of shots later, when Lilo and Stitch present his trick, the clock doesn't read anything. It turned itself off.
Continuity mistake: When Stitch first presents himself to Lilo in the animal shelter, his left ear notch vanishes completely as he turns his ears.
Deliberate mistake: In multiple shots, Stitch's ear notches move higher in places or vanish completely.
Continuity mistake: When Jumba attacks Stitch in the house Lilo's sandals keeps disappearing and reappearing.
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)
