Cerry the chicken is a chicken which works for The Agency, supposedly in Major Monogram's division. Her first name is unknown as she only appears in the series for brief moments. Not much is shown of her but she was seen in the Traffic Cam Caper episode. She was also seen in the episode It's About Time!, where she pecked at one of the evil scientists.
At the end of the episode 'Traffic Cam Caper, Agent C is seen trying to eat another Agent, Agent W, a worm. Whether this was just to tease the little agent, or that Agent C's natural instincts was making her attack her own allies is unsure. The reason for this may be however, that it's because Agent W was really working for the S.A.F and it may be that Agent C sensed his evil intentions. Agent C was assigned to help Perry and Pinky fight Benedict and Serum the Snail in Isculla, and the five are currently engaged in battle.
