Baby Diddy: When he was rejected from being a Star Child, he saw the other 6 Moon Children and decided to join them. He, along with Baby Wart, is the gardener.
Baby Waluigi: He wasn't happy when his star was taken back, so he joined the Moon Children. He's in charge of weapons.
Baby Wart: The young frog is a small moon child; the oldest one. He seems to look like Prince Froggy. He, along with Baby Diddy, is the gardener.
Baby Birdo: She was in love with Baby Yoshi, but couldn't be a Star Child. She decided that Moon Children was close enough. She's the cook, meaning they always eat eggs.
Baby Vivian: Baby Vivian is the youngest Moon Child, and was treated badly by Baby Beldam, so she joined the Moon Children when Daisy left. She looks like a Ztar with a red hat, because she hasn't formed into a Shadow Creature yet. She has no job.
