Wish Bear is shown with a tummy symbol in one shot after when she wishes Twinkers to Me Bear, Messy Bear, and Too Loud Bear.
When Messy Bear gets covered in chocolate, the floor is black.
When Messy Bear tells Twinkers that he wishes for a dozen eggs, his tummy symbol is mirrored. Also, when he gets eggs all over him, his starbuddy tummy symbol is missing.
When Wish Bear says "Hey!", her mouth doesn't move.
