The Crumbling Tower of Pizza is the twentieth and the final level in Pizza Tower, and the fifth level in Floor 5, Staff Only.

After the boss fight with Pizzaface and Pizzahead, Peppino must finally escape the tower with everything he has collected. The player must backtrack through the entire hub whilst enduring a barrage of enemies, transformations, and a final golf challenge, to reach the entrance of the tower and escape before it collapses.
