Deliberate mistake: When Lilo is told to think of a name for her "dog" while at the Aloha Animal Rescue, there's an adoption document on the desk. The document's paragraph is in fact an acknowledgment of appreciation for this movie's production. Although it's only briefly seen twice, there's sufficient time to read a few words, such as "project Lilo and Stitch" or "at Disney-MGM Studios," and particularly in the close-up as it's being stamped "making of Lilo and Stitch," the last words of the paragraph.

Deliberate mistake: When the roller skate with Scrump explodes, just as Jumba is blown backwards, notice the hallway's left wall with the doorway into the kitchen (this doorway is beside the stairs) is deliberately gone in this shot. That hallway wall with the doorway reappears properly in the next shot and a following shot. (01:00:30)
Answer: The movie contains two languages one is English, and the other is Hawaiian. Meega translate to I or me, and Quessta translate to destroy. I don't know what Nala means, people are telling me it means no or want, so essentially "I want to destroy".
Or it could be I no destroy but since they hate peace so much, they basically hate him.
