Pizza Sewers is the second secret area implemented into the game. The enemies here are not too threatening and should be no trouble. Health pickups in this area look like pizza slices. They will drop from enemies and destructible Pizza Box props.
This area occurs between 2-1 and 3-1. The game treats it like 3-1, which means that the Weapon Chest in this area drops weapons from 3-1 and below. After exiting Pizza Sewers, the game's difficulty is increased by one. The regular 3-1 area becomes equivalent to 3-2 in difficulty, which means there are more enemies and weapons start dropping earlier.

Trivia[]
- This area is a reference to the Teenage Mutant Ninja Turtles.
- The Pizza Sewers music was made by Eirik Suhrke, who also wrote music for games such as Spelunky, Ridiculous Fishing, Hotline Miami, and Adventure Time: SotNK.
- The Pizza Sewers theme is "What's That Smell".
- When killed, each of the turtles will scream the name of a color in reference to the different colored masks the TMNT have in most adaptations (the colors being Red, Orange, Blue and Purple).
if you overlap the theme with the teenage mutant ninja turtles theme, they are one and the same. plus, it sounds neat.
