The Underwhere

The Underwhere is a location in Super Paper Mario. It makes up one-half of the "afterlife" dimension.

Ruled by Queen Jaydes, The Underwhere (also called World -1 by the residents) is where people who have been neither good nor bad from "all worlds" go when they die. Once there, the people become what are known as Shaydes (a corruption of the word "Shades"). They typically chat about how they got a Game Over (such as being hit in mid-jump by a Micro-Goomba and falling into a bottomless pit). As the Underwhere is not a place of suffering and pain, just boredom and dullness, it should be compared to the greek Asphodel Meadows instead of the multi-regional Hell. Bonechill's prison, the place where people go when they have been very bad in life, is equivalent to Tartarus, also from Greek mythology. The Underwhere's counterpart is The Overthere, where the sinless can spend eternity.

In Super Paper Mario, Mario, Princess Peach, and Bowser are teleported "to the next world" by Dimentio between Chapters 6-2 and 6-3. The game acknowledges this as Chapter 7, and the beginning of The Underwhere is Chapter 7-1. It is here that Luigi loses his identity as Mr. L and joins Mario's party.

Throughout the beginning of the chapter, only Mario and Luigi may be used to open the Purple Door. Tippi, the Pixls that Mario gathered, Peach, and Bowser are all unavailable at the start (as is Luigi, until Mario finds him). Tippi and the Pixls become available at the end of Chapter 7-1 (when Mario and Luigi receive the then-revitalized Pure Heart from Sammer's Kingdom and return to Flipside). Neither Bowser nor Peach are found until Mario's trek through the Underwhere Road and the Overthere Stair, respectively.
