The following characters appeared in the episode "Super Gekko Muscles":
Gekko is in the town, busy lifting up several crates. He then notices the viewers and apologizes to them, stating that he is busy practicing his Super Gekko Muscles.
As Gekko picks up the sports equipment in the field, he explains how he loves being the strongest, especially since he is the smallest of the PJ Masks. However, he states that there is more than being strong when using his power. As he stores the sports equipment away in the shed, he hears something.
Night Ninja and his Ninjalinos, or rather the Ninjalinos, are throwing their sticky splats together in order to create the biggest Sticky Splat Boulder they have ever made. An angry Ninjalino hands Night Ninja a sticky Splat and indicates the boulder, as if to ask him why he is not helping them. Night Ninja defends himself by saying that he is figuring out who he can use the boulder on. He then notices the Gekko-mobile parked in the middle of the forest, and gets an idea. He orders the Ninjalinos to push the Sticky Splat Boulder down towards the Gekko-mobile to destroy it.
In response, Gekko runs over to the Sticky Splat Boulder and kicks it away, using his Super Gekko Muscles. However, it heads over to the shed where he just placed the sports equipment, and it gets destroyed. The sticky splats and the sports equipment are scattered everywhere.
Going back to the time where the Sticky Splat Boulder is just released, Gekko explains that he can get the job done if he uses his Super Gekko Muscles to their best use and not try to look cool in the process. He looks over to his left and sees that “the path behind the Gekko-mobile leads to the park with nothing to destroy there.” Taking this information, he uses his Super Gekko Muscles to stop the Sticky Splat Boulder from destroying his vehicle. Then, he pushes it away, and the boulder soon rolls away to the park.
Gekko recaps by saying that it is always great to be strong, but it is also important to get the job done. He then gives a wink to the viewers, and the short ends.
This short teaches that you should focus on getting a job done rather than looking cool doing it.
