This is Minchilla. Rejected by her kind due to being a cannibal, she became friends with Toy Springtrap and was introduced to the FNaVB gang by him. And when her ex tried to eat them, he was swallowed whole because she can grow and shrink in size.
I thought of the thing I done with Flaridox, then I thought of this thing after I looked at a pic of a similar monster chasing down an anime girl in a warehouse.
