The Little Fish are a group (of two or three) of fish who appear in every Bubble Guppies episode to help viewers learn the answers to any questions the Guppies ask. Easily amused and delighted, they swim to school with the Guppies and escort the home audience from segment to segment. They appear at the beginnings of episodes announcing the title of the episode.
Each of the Little Fish are an orange color. They have small black eyes and two fins each. In The Moon Rocks!, there was one and it was green.
The Little Fish have appeared in every episode of Bubble Guppies In The Title. Their first appearance was in Call a Clambulance!.
