It evolves from Nimblow when it is exposed to an Air Stone. It is the final form of Flowby.
Cirribus are based on clouds, and like the other members in its family, its most prominent feature is its head. Its head is large compared to its body, and the fluffy white structure on its head is based on hair. The rest of its body is comparably small, but it seems to be based on a woman's dress.
Cirribus can create numerous types of weather, such as rain, hail and thunderstorms. They are also known to conjure up winds of amazing strength.
Cirribus are known for being able to manipulate weather to destroy their enemies. They are extremely short-tempered and if anything disturbs them, they will let loose blizzards, thunderstorms, windstorms, and floods to drive them away. Cirribus also gather in large groups because since they are relatively small, they find good comfort in numbers.
Cirribus live in the atmosphere, and rarely come down to earth. However, if strong winds are blowing, it will force them to lower themselves to the ground. If they are forced to come down to earth, they become even more agitated than usual, and this is extremely dangerous for villages below, as Cirribus will take out their anger on nearly anything they come across.
Cirribus live very far up in the atmosphere. In rare occasions, masses of Cirribus would join together to form massive storm clouds capable of great devastation.
