Plasmoid Species in D&D Forgotten Realms | World Anvil

Plasmoid

Plasmoids are intelligent oozes that can alter their shape at will. Their amorphous bodies have a soft, malleable texture, and plasmoids can extrude up to five pseudopods, each one up to 5 feet long. They use their pseudopods for locomotion as well as for manipulating objects.

Every plasmoid has a mass of nerves for a brain. Plasmoids don’t have internal organs as humans know them, but they have pores through which they absorb oxygen. Up to four times in its life, a plasmoid can reproduce by joining with another member of its species. After this merging, the two plasmoids separate, and one of them (determined randomly) divides in half. When a plasmoid splits in two, one of the resulting creatures is the original, and the other is a physical duplicate that lacks the experience and knowledge of its parent.

A plasmoid talks by forcing air through tubular cavities in its body, giving its voice a whistling quality.
