King Baby is a royal baby who is the leader of the "Mini-game Babies." He ridicules anything that is not "royal" in his eyes. King Baby is very demanding and forces his friends to follow his every order, telling them that it will make them more "royal."
Mr Purple PJs is the "royal baby" of the Mini-game Island Babies. He is very proper for a baby, and serves the babies as a butler. He is often taken advantage of because of his kind personality, and will do as the other babies ask him without question.
