Continuity mistake: When the Wolf jumps into the lion's mouth at the zoo, one of the stripes on McPoodle's sleeve changes color and then reverts back. Also note, the stripes on Sergeant McPoodle's uniform sleeves repeatedly change between pointing down and pointing up (despite the reveal in the cartoon's last shot, all stripes should be identical).Super Grover
Continuity mistake: When the Wolf shakes the plastic surgeon, telling him to give him a new face, the surgeon's moustache disappears for a few frames. (00:05:30)
Continuity mistake: When the wolf tells the plastic surgeon to change his droopy face back to his usual face, the surgeon has a bald spot with a moustache. When the surgeon gives the wolf a mirror to see his new look, the surgeon is now completely bald and the moustache has gone.
Continuity mistake: When the convict trips outside the plastic surgeon's office, the sign on the window reads "plastic surgery" which changes to "plastic surgeon" in the very next shot.
