Character: trix rabbit
Ticks, better known as the Trix Rabbit is a food mascot for Trix cereal manufactured by General Mills. He is an anthropomorphic rabbit with a tall body and white fur.
The format in every TV commercial has changed over the years to varying degrees, but the same core formula still exists. In many commercials, he will always trick the kids into something so he can try Trix for himself without them knowing (mostly through a disguise or some contraption), but every time he tries to do so, it always backfires and the kids will say the infamous "Silly rabbit! Trix is for kids!" quote.
