Yes, but your fanart is not the only one that is used in a PJ Masks bootleg app, but there are other PJ Masks apps are using other people's PJ Masks fanart such as KingLeonLionHeart's image of Gekko with a cape.
Just to let you know, I renamed the page to "Papinuits (Cartoon Continuity)" since I needed to re-arrange and organise the page to be now labelled with "Cartoon Continuity" or "Original Continuity" with the name of their book version character names, you see I thought of an idea where other users would know which page is the character referring to by continuity while navigating in the wiki to prevent major confusion with book and cartoon versions of the characters. However, I left the character's English names in the contents of the renamed page so that the Moths page and the Papinuits page won't be confused as the same character from a shared continuity and story.
Also, I do want to confirm what Catlette4ever had said: I do want us to wait for the time being to add these storyboards and the new character in, as well as any concept art for Season 4. I don't want this wiki to get into any more trouble like it did before prior to Season 2's airing.
