"Fistful of Cereal" is the twelfth short of Foster's Home for Imaginary Friends.
Plot[]
Bloo tries getting a secret decoder ring from a cereal box. Mr. Herriman forbids him to get the toy without eating the cereal down to the ring. He then realizes that a secret decoder ring can decode his files on house residents and competes with Bloo in order to get the ring first. It is later revealed that Eduardo got the decoder ring before either of them started eating. He wonders why Bloo's file says he is a "doo-doo head," which Herriman responds by eating it.
