Revealing mistake: When the simulation starts, Wolverine is shown stabbing a guy with his claws. There is a blood splat on the wall, but there is no blood on Wolverine's claws. (00:02:15)
Revealing mistake: When the narrator says that Superman can leap a tall building in a single bound and shows Superman doing so, you can see in the background by some trees, an odd animation glitch. A curved, thin black line by the trees wiggling back and forth. (00:01:55)
Science Fair - S1-E1
Revealing mistake: As the teacher is walking up to Cassie's volcano experiment at the Science Fair, there are many people scattered about in the background around the room and at different exhibits. Except for Scott, the teacher, and Cassie, everybody else is perfectly still like statues. It's distracting, especially with them positioned all around supposedly mingling, walking, and looking at other experiments. Everybody is static. (00:00:05)
