Continuity mistake: When Nani, Lilo, and Stitch arrive at Mrs. Hasagawa's produce market, the parked truck has "Hasegawa" and a hibiscus on its door. The market's name and hibiscus vanish from the door when Stitch spins out of control with the hearing impaired market owner. Then, in the last shot of Stitch and the watermelon atop Mrs. Hasagawa, there's only a faint "Hasagawa" on the door, with an "a" now. Just to add, the market owner is listed in the credits as Mrs. Hasagawa. (00:42:20 - 00:43:00)
Continuity mistake: While Stitch, Nani, and Lilo are standing outside Kara's Electronics, the red TV has a VCR atop it, and the storefront window has two credit card decals at its bottom right corner. When Lilo asks, "What about Stitch?" the VCR is gone and the two decals are missing. Then, after Stitch snarls at the bicycle bell, the VCR is back, and the colors and style of the two decals change, though it reverts to the original way as Lilo shouts, "My friends!" (00:28:40)

Continuity mistake: When Cobra Bubbles shows up at the front door and confronts Nani about quitting her job, Stitch is holding a red book with its spine to his right; it then cuts to another angle facing Mr. Bubbles, and now Stitch is suddenly holding the book the opposite way with white pages to his right, before Stitch throws the book at the social worker's head.

Trivia: While Jumba is searching for Stitch in the house, Lilo and Stitch are sitting on top of the workbench as they're working on hiding an explosive device inside Scrump.

Other mistake: After Nani kicks the car's bumper and calls the driver a stupidhead, it's shown that the Pelekai house has exterior railing at the front staircase and balcony. While Nani's head is inside the dog door as she shouts at Lilo, when Mr. Bubbles walks up the stairs and nudges Nani's foot, at this particular angle part of the handrail or baluster should be there, but is deliberately missing in this shot. (00:15:20 - 00:16:00)
