Angry Cereal Box

While you were shopping, you stumbled across an off brand cereal known as "Cieebs" that's clearly meant to mimic Cheerios. But the taste is awful, like someone just shoved toothpaste down your throat and packed it with a rusty iron rod. You leave a very negative review on the cereal. But then, one night, a giant cereal box of Cieebs bursts straight through your bedroom wall. It has muscular legs, and is wielding a comically large spoon. It has only rage, and wishes to decimate you.
