Don't Dig Up

Don't Dig Up, also known as the "Remix Seed" is a secret world seed introduced in the 1.4.4 update.
The following seeds can be used to generate a "Don't Dig Up" world (case-insensitive):
== Changes ==
* The player now spawns in The Underworld instead of the surface.
* The world generates a trapezium-shaped but mostly flat Ash Block "island" in the central part of the Underworld where the player's spawn point is. It consists of Ash Grass and Ash Trees to help start housing in the Underworld.
* There are 3 underground layers (from top to bottom of the map): The first layer which appears to be the Cavern layer. The second layer which appears to look like the Surface biome by replacing most of the Stone Blocks with Dirt, Grass, and Clay blocks, forest trees and sunflowers generate on the grass. The third layer which is a Glowing Mushroom biome.
* The surface, the sky islands, and an outer 2 sixths of the world will be infected by the chosen world evil.
* Going through the top of the map will instantly kill the player.
* Fallen Stars that fall from the sky will not drop the item and instead damage players and NPCs if they’re hit.
* The Dungeon is painted with seemingly random Deep Paint, the walls inside are always painted black.
* Like the Dungeon, the temple is painted with random Deep Paint and the walls inside are always painted black.
** The temple spawns on top of the Jungle, where the surface is so you would have to mine all the way to the surface to reach it.
* The world will always be night. Attempting to change the time to daytime on the Journey Mode Power Menu will not change it to daytime.
