Bonnie and Skunk

Bonnie was a normal Wooloo until Halloween came around. Bonnie and some other Wooloo decided to play with a Ouija board and accidentally ended up conjuring demons. When the demons appeared, most of the Wooloo managed to roll away without so much as a scratch on them, but Bonnie got stuck and ended up critically injured. One of the demons, which Bon would later learn is named Skunk, made a deal with Bonnie, that if he was able to share Bonnie's existence, he would let her live. Skunk then took up residence in Bonnie's wool, able to communicate with Bonnie and the outside world and survive outside of Halloween. The face on Bonnie's side can move within the wool, talk, and make different expressions, as it's controlled by Skunk. Combined, they are known as a Wooboo.

Bonnie herself is very shy, but also very level headed, which is a good counter for Skunk's still mischievous ways. While Skunk cannot control Bonnie, he does try talking her into things that normally Bonnie wouldn't do, and together they level each other out so that Skunk can still have his demon fun, but Bonnie won't get in trouble. After a long while of being together, Bonnie has started taking a liking to pulling little pranks here and there, and Skunk has come to terms with toning himself down to coexist with Bonnie.

Bonnie and Skunk combine to make a Normal/Dark type.
