Other mistake: When Elastigirl is chasing the high-speed train, as she is in the middle of making her second final jump to reach the train, if one were to look closely, the train actually drives right past her before she lands. (00:31:40)
Other mistake: When Tom is being hit with the fruit, he is being hit high enough for Bee to see the fruit but doesn't react to random fruit hitting Tom. (01:00:15)
Other mistake: Vanellope steals a car from the Slaughter Race game and speeds off. Shank, the main character of the game, commandeers another car and chases Vanellope. When Shank's car is seen in Vanellope's rear-view mirror, the image is not reversed. Shank appears to be driving from the passenger seat.
Suggested correction: We see the mirror and it in fact is a mirror image of Shank driving.
Other mistake: Constantine is driving along a road and an big rig truck is heading for him head on. The truck honks and they both hit the brakes, stopping just a foot away from each other. But at the speed the truck was moving it could not have possibly stopped so quickly. It would have skidded into Constantine's car. (00:35:00)
Other mistake: Everyone arrives on set at the same time but somehow Beast Boy goes and returns to the toilet within seconds.
Suggested correction: This is a case of cartoon logic at play, and therefore is not a mistake. Within seconds of Beast Boy going to and out of the bathroom most of the other Titans also somehow go in and do their thing and then leave the bathroom right after each other with no real time between. This is just part of the silly world of this cartoon.
