Plasmoid

Plasmoid are highly intelligent and extremely dextrous oozes, able to manipulate every fiber of their being. Plasmoids can alter the fibers of their bodies to form interior pouches for carrying items, limbs to use as legs, arms, tails, heads, etc., and air pockets that can be squeezed to produce sound to talk.

Their nerves are massed into groups called ganglia. These can be sensitized to detect light, heat, texture, sound, pain, and vibrations.

When plasmoids sleep or lose consciousness, they lose their rigidity and ooze to conform to the area they are in. This can be a very dangerous thing for plasmoids, thus they select their sleeping chambers with great care.

Plasmoid Adventurers

Plasmoids love treasure and power. Thus adventuring has attracted their attention. Plasmoids enjoy philosophical debates, storytelling, and they are commonly employed in the political arena because of their near-tireless ability to speak about nothing at great length.

Plasmoids are easily entertained and nearly as easily fascinated. They have a child-like curiosity that frequently lands them in undesirable situations. One bad habit of plasmoids is their tendency to eat (absorb) things at random, occasionally things of importance to other beings.

Plasmoid loyalty is a thing of legend. Thus the saying, "If you want a friend to stick with you, choose a plasmoid." However, this doesn’t mean that they are beyond deceit.
