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, 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)

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.
