So in the episode "The Console", there's one scene where Gumball, Darwin, and Anais run towards what seems to be Gary's house, however, at the end of the transition, they're at the Robinsons' house. The reason I found this error is because a thing called "parallax", and I think you guys already know what parallax is. When looked at the perspective when the Wattersons' house is shown, it looks like they're running westwards, or towards Gary's house. The correct way was if they were running in the direction where their backs are facing the camera relative to the running scene perspective.
