Otyugh

Otyughs are strange aberrations that live in caves, crypts and sewers. They delight in the eating of filth and offal. Because of this, many civilized beings attempt to capture and contain otyughs within their city sewers to use as a means of garbage disposal. Despite its appearance and habits, an otyugh is surprisingly intelligent and capable of speech.

Description
Otyughs are strange-looking creatures, with round bodies that stand on three elephantine legs. They have a pair of tentacles that end in rows of sharp spikes. A third tentacle sprouts from the top of the otyugh’s body. This tentacle ends in a number of peering eyes. The body of the creature contains a massive fang-filled mouth. Due to the nature of the Otyugh’s appetite, their mouths are filthy and often carry diseases with its bite.
