The George and Harold, PJ Masks Power Hour 3: The Evil Robot
5 parts Complete The PJ Masks and George and Harold become bored with their very easily outmatched competition, so they team up and create a villain to fight. Their villain won't be evil and refuses to destroy him. Eventually, he does in turn attack Piqua from feeling neglected after The PJ Masks and George, Harold and Erica abandoned him.
Now the villain is putting citizens of both worlds into his own, alternative world like where he was born in and creating vacuums that would destroy the worlds where he has control over and is planning his revenge against The PJ Masks and George, Harold and Erica for abandoning him like that.
