"Catboy and the Shrinker" (also known as "Yoyo et le canon rétrécisseur" in French) is the first segment of the 4th Season 1 episode of PJ Masks.


By day, Connor, Amaya, and Greg were heading to the playground. Connor says he's finally tall enough to go on the big kids' stuff when Greg notices that the playground has been shrunk. The PJ Masks soon find out that Romeo and Night Ninja team up to shrink them. Catboy says that he's a big kid. But when Romeo and Night Ninja shrink him, Catboy makes the mission harder by complaining that he's so small.


The following characters appeared in the episode "Catboy and the Shrinker":


The episode starts off with Connor, Amaya, and Greg heading to the playground. While Amaya and Greg plan on going to the swings and merry-go-round, respectively, Connor is now finally tall enough to play in the big kids’ section. However, everything in the playground is small, as well as some of the objects outside the perimeter. The PJ Masks see more shrunken objects around the town that night and head into the forest when they see another object shrink.

In the forest clearing, the team sees Romeo driving a new invention: the Shrinker. He is not alone; Night Ninja and his Ninjalinos are also with him, although they fight over who is responsible for this scheme (Romeo handles pressing the buttons and driving the machine, while Night Ninja aims the blasting end of the hose). The other night was just a practice run for all of the things that have been shrunken so far. What, or in this case, who they really want to shrink is the PJ Masks; that way, Romeo will be able to take over the world, while Night Ninja will use them as his own PJ-linos to do whatever he says. They argue briefly about whose idea is better.

Romeo fires the Shrinker while Night Ninja takes aim. Catboy dodges the lasers and pounces over to stop them, but one hits him, and he is now small. The villains next fire the beams at Owlette and Gekko. Owlette grabs Catboy’s tail, and while she begins giggling at the fact that he now has a funny, but cute, squeaky voice, the team makes their escape as the Ninjalinos chase them, agreeing to get back to the Shrinker so they can zap him back to his normal size.

Catboy refuses the team to help him, however. Despite being small, he claims he is still a big kid, so he can do it by himself. He removes himself out of Owlette’s grasp and races over, only for the Ninjalinos to corner him and hold him down. They make him dance an Irish jig as one of Night Ninja’s actions for his PJ-linos, which even Romeo becomes entertained at, even though he cares more about taking over the world.

Gekko suddenly appears behind Catboy through his Super Gekko Camouflage and throws him towards Owlette. As the Ninjalinos chase them again, the team returns to the Cat-Car as Catboy insists that he’s not tiny. He becomes frustrated when he realizes that he can’t drive his own vehicle and bangs on the steering wheel. He is shot out when it loses control, but Gekko catches him and offers to drive instead. The PJ Masks escape before the ninjas could catch them.

As they drive around, the team thinks of a plan to turn Catboy back to normal, which will need to involve all three of them. Catboy decides that they should quickly drive around the villains and make them dizzy; this will give him a chance to grab the Shrinker. Owlette and Gekko are unsure about this, knowing that the invention is big, and he is small, but he insists, believing that even though that’s the case, they don’t need to do things differently.

Gekko drives the Cat-Car into the forest and drifts around Romeo and Night Ninja. As expected, the two villains get dizzy and fall off the Shrinker. Catboy exits the vehicle and pushes it away from them. The invention rolls off, but it hits some bumpy tracks, causing it to activate. Catboy also flies out, and he shrinks even more. Owlette and Gekko find and retrieve him through Owlette’s Owl Eyes while Romeo, Night Ninja, and the Ninjalinos run after the invention.

Despite the team’s efforts to cheer him up and think otherwise, Catboy believes that he is now useless because of his really small appearance. When he jumps off Owlette’s hand, Gekko almost steps on him as they look for him, even though he is right by them, further proving his belief. Catboy suddenly realizes that being small may actually be a good thing because he acts as if he is invisible. The team can use this to their advantage to get the Shrinker, as long as they work together.

The villains eventually retrieve the Shrinker and are at the sports hall where the Ninjalinos are performing their Irish jig to entertain Romeo and Night Ninja. Not as impressed as he was before when Catboy was with them, Night Ninja decides to use the Shrinker on them. When he zaps one, Romeo zaps him back to normal, and another argument between the two initiates about working the invention. They stop arguing when Owlette and Gekko confront them and attempt to zap them.

Meanwhile, Catboy is behind one of Night Ninja’s legs. He climbs up to tickle him, causing him to throw the hose and Romeo to adjust the controls. Catboy returns to his normal size when the invention is activated, but not for long; he shrinks again when the hose hits the ground. The villains unsuccessfully try to pull the hose away from Owlette as she grabs it. After Gekko frees himself from the Ninjalinos holding him down with his Super Gekko Muscles, he catches it.

The Ninjalinos run over to get the hose back. One of them dances on top of the controls to prevent Owlette from using them while also shrinking, then enlarging some of the ninjas. Another one sees this as a chance to get bigger. He goes in front of the hose, although once it activates, Catboy climbs up the Shrinker, jumps in front of the beam, and is finally back to normal. All the villains retreat as the PJ Masks zap the Ninjalinos into a smaller size and threaten to shrink Romeo and Night Ninja as well.

The team proceeds to zap everything back to normal. Once that is finished, Owlette adjusts the controls while Catboy points the hose at the Shrinker itself; it shrinks to the point where it disappears forever. The PJ Masks exclaim their signature victory phrase.

The next day, Connor, Amaya, and Greg go over to the height board at the playground. Amaya and Greg offer Connor to go play on the big kids’ section, but he declines. He’ll stay on the small section for the time being with his friends until they are tall enough to join him. They play on the merry-go-round as the episode comes to a close.


  • No matter who you are and what you are, you can think big thoughts (be courageous).
  • Don't brag about yourself.
  • Instead of being upset about your disliked abilities, you can use them to your advantage (don't think how you are the same as others).


  • Romeo introduces the Shrinker in this episode.
    • Only Catboy and the Ninjalinos were shrunken in this episode.
  • This marks the first time two different villains side together to go against the PJ Masks in this episode.
  • Even though Romeo and Night Ninja sided together, they didn't seem to get along.
  • Gekko drives the Cat-Car for the first time.
  • Night Ninja and his Ninjalinos meet Romeo for the first time.
  • This is the first time two villains appeared in one episode.
  • The Netflix version of this episode cuts Night Ninja's line where he calls Romeo a "stumbling buffoon," shortening it to "Who're you calling dizzy?"
    • The line may have been likely shortened due to it sounding too suggestive/rude towards younger audiences.
