The Pizza Universe is a dimension where Pizza and humans are in the opposite roles than they are in the real world.
The inhabitants are anthropomorphized slices of pizza with arms, legs, eyes, and mouths and pizza is made out of human beings. Different races of people are the different toppings. The three known toppings so far are Caucasian, African American, and Hispanic people. They show an affinity for eating humans and even display preferences for different ethnicities.
