Trix is a cereal produced by General Mills. It consists of ground-corn pieces that are sweetened and fruit-flavored. The pieces used to be fruit shaped as well, but have since reverted to their original sphere shape since 2007.
the mascot for Trix is the Trix Rabbit. He is constantly trying to get Trix, but the children in the commercials do not let the Trix Rabbit near their cereal. This has spawned the massively popular slogan "Silly rabbit, Trix are for kids!"
