To excerpt from an excerpt:
Tier Zero is the industrial core inherent to every Beems in existence. It consists of a neoplastic layer of skin inside the Beems’ ventral carapace. Situated in front of the reproductive organs and behind the neural cluster, it is directly and indirectly responsible for all the growth a Beems will undergo in its lifetime. After a schematic is uploaded into the Beems’ Drone Management Array, the DMA removes a portion of the neoplastic compound and guides it through several different chambers for manufacture and preparation. The different chambers may vary, though most Beems have a civic chamber, for the production of furniture; a culinary chamber, where the material is laced with nutrients and grinded into different types of foodstuff; and a growth chamber, where the material is infused into the beems’ superstructure, allowing it to mature into an adult beems. The growth chamber later becomes a vestigial artifact, replaced with more specialized chambers depending on the gender and the specific class of beems – an excerpt from ‘Your Biomechanoid Starship and You.’ Section 447-1-A.

Yeah, basically that ^
