Oozemen are freakish creatures, half-[[human]] and half-blob. Of their human bodies only remains a head (composed of the skull, the brain, eyes, and teeth) and the bones of their hands.
The layer of ooze that covers the remaining human body parts seems to act is in fact blob matter, same as that creature's "skin" in [[green blob|green]] and is identical to that of a [[yellow blob|yellow]] other than blobs. It acts as both that creature's skin and body, and has a bright, toxic green coloration. It is not fully understood how, but the blob half seems to possess a nervous connection with the human brain, and it can heal and regenerate any damage that the head and hands sustain, even to the brain. It is believed that the blob core is the creature's true central nervous system and that the brain fulfills little actual purpose.
Scarily, oozemen appear to understand spoken language. Although they cannot speak or make any kind of vocalized noises (they lack vocal cords), they frequently and very expressively emote laughing, smiling and sneering expressions. With the gooey layer of blob that covers them dripping over their faces, it gives them a grotesque and evil appearance, and it seems that these creatures are fully aware of their freakish, horror movie-like appearance, as they enjoy terrifying sapients.
