Somebody uploaded trailer for Rayman Related thing that nobody knows what is this : https://www.youtube.com/watch?v=WrozSDaCUtw
RayWiki thinks this is game : https://raymanpc.com/wiki/en/Rayman_Adv ... lled_game).
But I'm thinking this cartoon, because this trailer had almost same plot what in Rayman 2, and it's hard to believe that Ubisoft would like to do the same and call it a new game, even Rayman 2000 I can't name this, maybe this is come to be spin-off or cartoon. In my opinion, there may be a cartoon, and exactly a pilot episode for this cartoon.
I will also say that the person who posted the film on Youtube did not reply to any of the comments under the trailer and posted the last film in March 2019.
Someone will help me verify what it is and discover some information about it, because this trailer is the only information and the only source that something like that exists

Last Words : Models in the trailer look like those from Rayman Arena cutscenes.
