Continuity mistake: Lilo and Stitch catch Clip at the Birds of Paradise Hotel sign. Clip goes around behind the sign, and then Lilo and Stitch get on the front side of the sign and jump around to catch Clip. As they are walking away, suddenly Captain Gantu is hiding behind the front side of the sign crouched down and stands up once they leave. He just appears there, and as big as he is there's absolutely no way he snuck up and crouched behind the sign without being seen by the camera. He just materializes there. (00:03:35)
Mr. Stenchy - S1-E4
Continuity mistake: The second time that Jumba shoots Gantu with the orange string that wraps him up, the highest it gets is his shoulders, however, when Gantu falls to the floor, the string is now in three ringlets above his forehead.
Continuity mistake: When the old lady holds out the bracelet she made from Experiment 606's ball, it suddenly gets much smaller in the close-up shot, having shrunk down. The other charms on the bracelet also change, and the position of her thumb moves. (00:01:50)
Continuity mistake: Hamsterville climbs up the ladder and pokes the hamster watering thing, and a little pours out, but when he climbs fully atop the platform, the puddle of water has disappeared.
Hunkahunka: Experiment 323 - S1-E33
Continuity mistake: Stitch turns off the lights and a minute later everyone falls in love with Pleakley. He stutters and screams as he's chased away. One shot later, Pleakley is still by the door and the crowd in its original place. The in between shot of Lilo would have shown the crowd running back, and there was no audio signifying their return, and the shot didn't last long enough for their return anyways.
