Ball Dolls are egg-shaped robotic dolls. They have an angry expression and are very aggressive. They wear a green dress with a yellow bow on their heads. They have small, black eyes, brown eyebrows, pink blush, red lips, red shoes, and they hold a gift box wrapped with a blue-white plaid paper and a pink ribbon at the top.
They walk toward the player and then a red head with a white bonnet pops from the gift box shooting balls from its mouth. They can also inflict damage through direct contact.
