Clucks is the chicken of Pacifica Southeast. She is believed to win it at the fair, like how Mabel Pines won Waddles. Clucks's role is semi-big in the series and appears in the majority of episodes.
Not much is known about Clucks. It is known it is white with a yellow beak and some red features like an ordinary chicken, but it wears a sparkly collar so it doesn't get lost. It is most likely based off of the same type of chicken that Pacifica Northwest wins in The Time Traveller's Pig, seen pecking her repeatedly in the final timeline where Mabel wins Waddles again, and Dipper loses Wendy to Robbie.
