Bloodsauce Dungeon is the fourth level in Pizza Tower and the fourth level of the Tower Lobby.
The level is an almost entirely vertical, bone-filled dungeon, with different layers the deeper you go.

The level's titlecard shows Peppino and Gustavo, the former in a viking-like outfit while holding an axe while the latter is wearing more typical knight armor while holding a torch, in a dimly lit section of the dungeon, stalked by a menacing-looking Pencer and Cheeseslime inside of a giant skull.
