Other mistake: During the Pokérap, when the Poliwrath name is said, the Pokémon shown is actually Poliwag. Also, when the Graveler name is said, the Pokémon shown is actually Geodude.
Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
The Planet of Dr. Moreau - S1-E4
Other mistake: When the mountain starts to collapse, the Silver Surfer and the enslaved trolls begin falling to the ground below at a rate comparable to what the falling rate on Earth would be. The Surfer is able to catch himself on a ledge and absorb his restraining collar into himself, granting him control over his powers, which he uses to prevent the trolls from falling to their deaths. With the amount of time the Surfer spent struggling to overcome his restraining collar, the trolls would have already fallen to the ground.
