"PJ Robot Malfunction" (also known as "Les Pyjamasques et le robot detraque" in French) is the second segment of the 21st Season 4 episode of PJ Masks.
Romeo takes over PJ Robot so he can use him against the PJs.
The following characters appeared in the episode "PJ Robot Malfunction":
PJ Robot is working on upgrades for the PJs' gear, however his attempt fails and briefly causes the PJ Seeker to go haywire. Although the damage is minimal, and the PJs assure him it was an accident, PJ Robot feels bad about his failure. As he cleans up the mess and takes it out of HQ, Robot, who was hiding behind a bush, shoots PJ Robot with a mechanical bug. With the bug, Romeo takes control over PJ Robot.
The following day, Connor, Amaya and Greg find the box with trash next to a trash can, and knowing PJ Robot would never litter on purpose, they fear something happened. That night they transform into the PJ Masks to check on their friend. Once in HQ, PJ Robot uses the PJ Picture Player to alert the PJs about the Wolfies, Luna Girl and Night Ninja causing trouble in the city. The PJs split up and head into the city with their respective vehicles, but don’t find any of the villains since the footage they saw was fake. In HQ, PJ Robot tries to resist Romeo’s control, to no avail.
Romeo forces PJ Robot to remotely take control of the PJs' vehicles, and send them out of control. After having some fun, Romeo orders PJ Robot to get the PJs back to their HQ, and once they are inside he has PJ Robot activate rocket ship mode. By now, the PJs realize something is wrong with PJ Robot. They try to abort the launch, but the systems are jammed. All they can do is buckle up as HQ takes off into the sky.
Unfortunately for Romeo, his Flying Factory is in the path of HQ and the two are now on a collision course. Romeo quickly orders PJ Robot to steer HQ away from the factory, which he does. A crash is averted, but the fact that PJ Robot avoided the factory tips off the PJ Masks that Romeo might be behind this. With her Owl Eyes, Owlette finds the bug and realizes what is going on. Since the PJs suspect Romeo might be spying on them, they pretend to give up and to let HQ fly into space. Romeo falls for it. As soon as Catboy hears Romeo has dropped his guard, the PJs break out of HQ and attack the factory. Catboy takes the remote control from Romeo and destroys it; while in HQ, Gekko destroys the bug. Now that PJ Robot is free, he flies HQ to the factory to pick up Owlette and Catboy, while also incapacitating Robot, Robette and the Fly Bots with the Mega Meow. The PJs regroup in HQ and shout their victory cry.
