I've been able to find most of the movies from my chldhood due to remembering certain actors and using the power of Imdb. But there was a series of cartoons that i faintly remember, they were probably French or from Belgium. It was short cartoons about a group of young people who spray painted walls (atleast in the intro) and the main character had hair a bit like Tintin and a very round head. I think they spoke nonsense (or perhaps a foreign language, but there were no subtitles or attempts at translations so i assume it was nonsense). There was something about a bumbling cop who chased the main character around, i think.
Also, and now it's getting obscure, there was this french comic thingy i bought on a vacation. One of these books where you have to collect images, it was something about a young boy who encounters dinosaurs (perhaps through either VR or by time travel). Only vaguely remember it, but it seemed like it was a thing outside of the collection comic.
