Lost Underworld

The Lost Underworld is a location in EarthBound. It is reached by going through a hole in Lumine Hall. The Lost Underworld is tremendous in size and seems untouched by time and modern innovation. It is home to dinosaur species and Tendas. Deep into the Lost Underworld, is Fire Spring, the last Your Sanctuary location.

In EarthBound
The Lost Underworld first appears after defeating the Electro Specter and gaining the melody of Lumine Hall. It is used as the only exit from Lumine Hall. When Ness and his friends first go to the Lost Underworld, the player can notice that the sprites of the characters are noticeably smaller, emphasizing the largeness of the area. Inside, Ness will find dinosaurs, showing that the area is almost unknown and untouched by time. There are also geysers that shoot out red or blue water, healing HP and PP respectively. Talking to the Tenda villagers here will show that the dinosaurs are actually in "cages", although it appears that the Tendas are in the cages. Ness and his friends must reach the end to get to Fire Spring and record the eighth melody.
