Molly is a main character and one of Mr. Grouper's students in Bubble Guppies. Her best friend is Gil and they seem to act like the hosts of the show. They always appear in the intro of each episode, which adequately touches on the topic of the episodes. She always starts by saying "Hi, it's me, Molly and it's time for..." with Gil usually interrupting by doing something silly. She has a love for singing more than any other character in the show.
