The ugly acolytes, Ninjazouaves and Papilunes, join together to become one super villain. Gluglu then learns to put aside his pride and work hand in hand with Bibou and Yoyo to stop this new demonic team.
The following characters appeared in the episode "Ninja Moths":
The Ninjalinos and Moths work together to kill off Night Ninja and Luna Girl by sending them off into space (despite the latter's Luna Magnet giving her the ability to breath in space) instead of being their sidekicks, unless the PJ Masks stop them first.
However, they're not the only villains who have shown psychopathic traits, as Roméo Mécano and Sorceline are implied to be more evil than they are, such as showing malicious intentions on physically harming people with lethal weapons and causing any socialogial suffering to the Animal Totems (by permanently locking them inside a cloud of Mitomites), while the latter's cartoon counterpart got more violent in Seasons 2 and 3 than she was in Season 1.
This is the second episode where two PJ Masks members say "Time to be a hero!".
Gekko can be heard saying "I hate Sticky Splats!" This is the third use of the word "hate" in PJ Masks, which could be suggestive/inappropriate for some viewers.
Both the Ninjalinos and Moths are referred to as "ugly" in the French description, even though they're not really hideous-looking. However, the referred name may mean to describe how bad these acolytes are.
