Underworld

The Underworld is an location that appears in Conker's Bad Fur Day and its remake, Conker: Live & Reloaded. It is where Gregg lives. Visiting the Underworld is optional, as Conker only briefly visits there if he loses all of his lives the first time. Conker first meets Gregg here if he first loses all of his lives before encountering Gregg at the pier in the Spooky chapter. In the original release, the location is pitch black and lacks any decoration, but in Conker: Live & Reloaded, it features some interior decorations such as tombstones and light blue lanterns.

In the Underworld, Conker learns about Squirrels' Tails from Gregg. Once he grabs a Squirrels' Tail, a giant skeletal hand drops down from above and returns Conker to where he most recently visited.
