Custom Superflat

Superflat (sometimes called Flatlands) is a world type replacing the normal varied terrain of the Overworld with customizable layers.
On a classic superflat world, the terrain consists of one layer of bedrock, two layers of dirt, and one layer of grass; the surface of the world is completely flat and at height y = 4, with the exception of villages and terrain features, if they are enabled. Since the height limit (256) is unchanged, there is then slightly less than one-third more vertical height available to build above-ground structures as compared to a normal world. Mobs spawn as normal, including slimes.


Because of there being chests in villages, and villages frequently spawning near the spawn point, it is possible to use Superflat as a survival challenge map. However, the high amount of slimes makes this extremely difficult to an inexperienced player, if playing on any other than peaceful difficulty.
The Nether and the End both generate normally (With the exception of the Console Edition for the Nether)That's a lot of tnt
