What is the name of an old french cartoon show that had two guys with wings on their head?

You're probably thinking of "Les Minipouss" (The Mini-Pussies)! This show was popular in the 1980s and featured two characters, Pit and Pouf, who had little wings on their heads.

They went on adventures, often getting into trouble with their mischievous nature.

Let me know if that rings a bell!
