why schoolbuses? also, 3 -> three
Compared to the original design, the Doom 3 mancubus is more elephant-seal- or [[Wikipedia:Cthulhu|Cthulhu]]-like (the ''Making of Doom 3'' book points out the latter as a source of inspiration). The strange head was explained by the game designers: the centre tentacle is a breathing tube, consisting of tiny holes along its sides (which are visible if viewed closely), while both side tentacles were actually supposed to be tusks. Due to a graphical and model design glitch they were reduced to feeding tools, and are stated to be used like the mouth of an [[Wikipedia:Octopus|octopus]]. It is unknown whether they have a beak inside their mouth or not. In Doom II, the mancubus had a mouth, leather-colored skin, and elephant-like feet. In Doom 3, the mancubus has a small "trunk" instead of a face, pale skin, and their feet look like fanned out pieces of flesh at the end of amputated legs.
