Title card gallery
The third season majorly focuses on the temporary transformation of already-existing characters; these characters would be Teeny Weeny and Kevin (briefly).
Starting with "Moon Madness," Season 3 also seems to majorly focus on crystals.
The episodes that end in the day are toned down drastically to the point where there's almost no episodes with this feature.
In a similar fashion, episode title cards that feature a PJ Masks' name has been toned down to the point where there are almost no episode titles mentioning a hero's name.
It is noticed in some scenes where an episode begins in the night, the PJ Masks no longer wear their pajamas before the transformation and now wear their daytime outfits.
This was previously seen in Season 2, but it wasn't as frequent than Season 3.
Luna Girl starts to be called by her nickname, "Luna," more than her full name.
This is the last season Kyle Harrison Breitkopf voices Gekko.
As of this season and onwards, the episode title cards are no longer color-coded depending on what character is focusing. The title cards will now always be highlighted blue (with the exception of "Lionel's Powers" for this season, as it is highlighted green).
As of this season and onwards, the intensity of the missions the PJ Masks faced in some of the episodes toned down to feature little or no fighting sequences and focused more on the main problem in most parts of the episode.
It also featured plotlines that wouldn't normally happen as part of the series' premise, as well as parts of the plotlines that look unnecessary and pointless.
In response to these flaws of the series, some of the viewers disliked certain episodes that had those aspects.
