Ideas of questionable quality

Limbcritters but they can attatch, detatch, and reattatch themselves to/from their ling and people who are missing the right limbs. Attatching to a non-ling would give control of the limb over to a limbcritter but the limb would function better than a normal one, legs would be faster, hands could function simultaneously, eyes would see better and have abilities to highlight things for other limbs and the host to see, and buttcrabs could fart on no cooldown.

It'd have a lot of fun uses like replacing the crews limbs with evil ones, or having limbcritters get painted and assemble onto someone like power rangers, but I imagine this would be hard to code.
