We encountered the Otyugh in the a forgotten passageway in a stronghold of the orcs. It was hiding underneath a pile of refuse which is common for this type of monster. They feed off mainly trash and that is most likely what it was doing underneath their hideout disposing of their refuse. Standing on 3 legs it has a wide mouth, 2 feeder tentacles and one that it also uses for vision. It was rather easily dispatched and it smelled horrible.
A sample of its blood is kept by Magus.
