Pluto is a planet that the player can visit using the Disk of Chiron. It is mostly made out of Plustone. It has clouds of Plusmoke. When a player mines low enough to reach what would be the Underworld, there is instead the Core of Pluto. Pluto has more caves than a normal Terrarian world would have, with tunnels everywhere, like a maze. There are 5 Shrines of Chiron hidden somewhere beneath the ground, and to escape Pluto you need to find all 5 of them and get the Plutrite Artifacts. The background of Pluto is purple, and there is little to no light. No trees grow (no duh), and there is no dirt.
