You'll see her alot in the future. She's was a character I made because of a game called LINE PLAY. You could make animal people or just people rofl. She didnt have pink sheep hair, but she was a cute sheep. One day there was a Show by Rock! collab in the game and saw there was a pink sheep girl who was very cute. I even watched the anime and I loved the show.
So I changed my sheep's hair from white to pink! The story goes her sheep fur hair changed colors due to obtaining the ability to travel through dimensions.
