The background of the boss room from Labyrinth, the third stage of Parodius Da. It's a stage where the player navigate accross a food castle, dealing with all the sorts of food-related enemies, and a very strict path. The boss from this area is Hot Lips, who, like the name says, are a bunch of flying lips who thrown their dentures against the player. Maybe some bonus or castle area would work.
Uses palette 3. BG1 and small part of BG2 are used.
