Mini-Villus
The Mini-Villi are a species of hair who were searching for their "promised land" with their Mini-King for centuries and eventually found Rayman when he was bald, so they planted themselves onto Rayman's head.
Raynette, the wife or girlfriend of Rayman was furious about him not being bald as she enjoyed him without hair, resulting her in attempting to cut them in half. Luckily, they learned to use the Helicopter or possibly the Super Helicopter to get away from her possibly forever.
These technically appear in every Rayman game but are revealed to be alive in the PlayStation Vita version of Rayman Origins
