Lunar Base

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.

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, 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.
