Continuity mistake: In the scene where the robots run out of battery, the female robot stretches out her right arm and shuts down in that position. The male robot walks up and stretches out his right arm and shuts down holding hands. In between shots of holding right hands, you see them holding left hands. First right hands, then left hands, then right hands again.
Continuity mistake: When Yosemite Sam tells the devil that he has "the very varmint in mind", you can see there are no flames coming up from the pit behind him, but in the next shot flames have suddenly appeared.
