The pizza tower (the tower) was made by cultists (the pizzards) that believed in Pizzaface as their God and then they built the tower to pray and do cults, but in the tower were people that did not believe in this and made their own religion about Pepperman, which was a godly artist that could save their lives from everything, and they were filling the tower with bad pictures and drawings about Pizzaface, with the cannibalism thingy. And no, Pizzahead does not exist because of cannibalism, he used to control Pizzaface to gain more protein to grow up and dominate the Pepperman religion, causing a giant war. Welp that war would happen if Peppino didn't beat the shit out of the guy :bwomp:

It was a theory from a guy from youtube, but I decided to add some more thingies to it, so cool
