Got some other ideas so those might show up later

Sleeple, The Dream Sheep Pokemon (Fairy type)
Its soft, sleep inducing wool is popular among insomniacs. Sleeple are commonly high energy and playful, making them quite a handful.

Nitewool, The Nightmare Sheep Pokemon (Dark/Fairy Type)
This protective pokemon will give nightmares to those who hurt ones dear to it. Despite its appearance, they are a complete goofball.
