Pinky and kitty doll

Pinkie doll is evil. Pinkie Doll looks the same as Kitty Doll, she has curly hair, just like the one Pinkie Pie does, giving her her name, and she's not stuck with a permanent smile.

Kitty doll: Kittydoll is a sadistic killer who seeks revenge, her goal is to ruin Katherine's life by killing off her friends one by one. She has pale blue eyes with two pupils that look like the letter X, two eyelashes on the edge of each eye, a green shirt sewn to her hands and neck, a pale blue skirt sewn to her waist, bright pink hair that reaches her back, and a short pink tail.
