Lunar Base

This article documents an April Fools' joke.

This feature was exclusively part of a joke version and is not currently planned for addition to regular Minecraft.
It is documented here on the wiki due to being officially-released content by Mojang Studios, even if not present in a final version.

This feature is exclusive to Java Edition.

The ACME Self-Building Lunar Bases are joke features that can be found on the moon.

Generation

Lunar bases generate in the moon biome. They have a ¹⁄₁₀₂₄ chance to generate in a given chunk. ^{[more information needed]}

Construction

Lunar bases look similar to a moon rover at first, with a dropper renamed to "ACME Self-Building Lunar Base" at the center. Pressing the golden pressure plate located on the rover, however, will start building an enormous lunar base. Adding objects to the dropper does not seem to change construction, although having blocks above it will prevent it from starting to expand.

Blocks

The structure contains the following blocks:

The dropper that activates the structure building has a special tag 'Lunar', and can be obtained through the command setblock ~ ~ ~ dropper{Lunar:1b}, and can be activated by a light or heavy weighted pressure plate placed above it.

Issues

Lunar bases are unsupported due to being an April Fools' joke, and therefore such issues relating to them will not be fixed.

Trivia

The "ACME" at the beginning of the lunar base's full name is likely a reference to the "Acme" threading put at the beginning of various' companies' names in the late 18th and early 19th centuries as a way of having said companies' names appear near the top of alphabetical lists, popularized as a generic company name by the fictional Acme Corporation of the Wile E. Coyote and the Road Runner cartoons.
- While stylized as an acronym in-game, the term "acme" comes from the Greek ἀκμή (acmḗ), meaning "peak", "zenith" or "prime", though backronyms such as "A Company Making Everything" and "An American Company that Manufactures Everything" are popular folk etymologies.
