The Whirly Dirly Conspiracy - S3-E5
Continuity mistake: When Beth glues the horse hoof on, the bottom is facing up. In the next shot it facing to the side. And then the leg changes shape in different shots.
Continuity mistake: When Ruby volunteers to search the barn while infiltrating the Ruby Squad, she throws up her hands, revealing both palms and the fact that her gemstone, which should be on her left palm, is missing in this shot.
Continuity mistake: When Katana removes the armor off her, it lies in pieces around her feet on the ground. However, in a later shot, when she comes out wearing her eye mask and katana strapped to her back, the armor disappears altogether.
Continuity mistake: Sometimes Cyborg is waterproof and sometimes he isn't.
