Gil is Molly’s silly, rambunctious co-host. If he sees a ball, he must throw it; if he finds an electric guitar, he has to play it; if there’s a pig costume around, he’ll be oinking in no time. Gil’s upbeat energy and never-ending curiosity are infectious, and he encourages others to join him in goofy, playful adventures.

This girl has star power! Molly’s super smart and her bubbly personality makes her a great friend and co-host alongside Gil. She’s also a great singer who inspires every Guppy and land-dwelling preschooler she encounters. Molly always makes sure to talk directly to the audience, ensuring they stay at the center of all the action.

Goby is a creative Guppy with a vivid imagination who loves putting on costumes, telling stories, and speaking in silly voices. Luckily, Goby does not keep his imagination to himself – he uses it to invent exciting adventure stories for his friends to act out in the classroom and on the playground.

Zooli is a kind-hearted, spunky girl who is definitely not afraid to get a little bit messy! As the animal expert in the Guppy group, Zooli loves sharing fun facts about creatures big and small, especially her pet frog Izzy. When an animal is in need, she’ll be the first to help

Nonny is brainy and not always the most enthusiastic Guppy. He’s more likely to comment on the action than get swept up in it and has an advanced vocabulary for his age. Physical activities make Nonny a little unsure of himself; he’d rather define “basketball” than play it. Even so, Nonny is always willing to keep trying, especially with some encouragement from his friends.

Oona is sweet, gentle, curious, and always looking out for her friends and their emotions. Whenever a fellow Guppy is sick or feeling down, Oona is the first to be there with kind words and care.

These Little Fish seem to have all the answers! They happily swim to school with the Guppies and are always excited to learn and play along with them. Whenever Molly and her friends have a question, the Little Fish are there to share what they think is the answer.
