Peas is a tiny pea-like imaginary friend who wears a thimble as a hat. He appeared in "The Little Peas", a retelling of the episode "The Big Cheese". In this episode, he is the only friend still in the house and tries to open the door when all the other friends have been locked out by the new security system. When he gets outside he climbs in Frankie's ear and convinces her to turn the broadcast around and use it to ask for charity. He also was seen "The Bloo Superdude and the Great Creator of Everything's Awesome Ceremony of Fun That He's Not Invited To" where Bloo almost stepped on him, and "Bad Dare Day" where Bloo dared him to knock a battery off his shoulder but failed due to his small size.p
- Peas is possibly the second-smallest imaginary friend in the series, with the smallest kind being the Fleas.
