Part of the evil woman's hair is missing for a second in the scene in the hotel room.
When the descendant of Queen Madula is in the hotel room where she has just turned the scientists into stone, her back is to the window. Then in the close-up shot in the next scene, her back is against the wall.
(Puggsy and Fangface approach the evil woman dressed as hair stylists)
Fangface: What do I do, Pugs? What do I do?
Puggsy: Try teasin' her hair.
Fangface: Ooh-ooh, okay Pugs! Tease it! (makes faces at her hair) Nya-nya-nya-nya-nya-nya! Nya-nya-nya-nya-nya-nya!
Puggsy: Aw, shut up.
