Moonglow is 7 years old in age, and she acts rather odd. She sometimes feels pain in random parts of her body, and she wears big, heavy boots which drag her down. Even with her derpy faces, she is loyal to Starshine and Wade. Moonglow doesn't seem to have much of a backstory, since she was only made to be a sidekick to Starshine. Her voice is known to be extremely immature and high-pitched.
