The Underworld is a location in Skip and Sqak and its also the place Dib works at. It can only be visited once in the game, after getting killed for the first time, Skip and Sqak awoke in a Dark gloomy cavern like area with grave stones and skulls. The Underworld does not have flames or pain, just boredom, fear, dullness, and darkness. It is a place where all bad souls go after they die (which is strange why the duo went down there instead of heaven).This world is not very long, instead you have to walk over to a Heart Fruit near by to go back to the living world.
