↑ ab83 blocks buried in the cellar room are generated as sand initially. 5 to 7 of these are replaced with suspicious sand in random positions.
↑ abcOf the 25 blocks which make up the cellar room's collapsed roof, 33% is sandstone, while the rest is sand. One of these blocks is replaced with suspicious sand. On average, the cellar roof consists of 8 sandstone, 16 sand, and 1 suspicious sand, which this tally reflects.
↑Additional layers of sandstone may generate from the base of the pyramid to the ground.
NOTE: Red, green, and blue wool do not actually generate. In this blueprint, they represent:
Red wool: Blocks buried in cellar room, which consists of sand and suspicious sand. Consult #Materials for generation rules.
Green wool: One sand block and one sandstone block. They are mutually exclusive (i.e. if sand generates in one position, then sandstone will generate in the other).
Blue wool: Blocks which make up the collapsed roof of the cellar room. Consult #Materials for generation rules.
