Revealing mistake: Cottontail gives Tom a wet Willie. However Tom reacts before Cottontail touches him.
Revealing mistake: After Robin starts to believe that the Teen Titans are in fact a joke, he gets sad and goes out a hole in the wall saying goodbye to them. He fires his grappling gun up and steps out of the wall. But his arm remains bent as he stands casually in the air to be taken upwards. There is no effect of gravity or any realistic body motion in those moment. As his weight should have had him dangle down with his arm stretched out above him and him swaying like a pendulum. Instead he appears as a stationary action figure in a single pose with his elbow bent as he's taken up.
