The hexagoon is a large, bull-like monster covered in a thick, tough brown hide, with a peach underside, and a yellowish-green mane and tufts of hair around its feet and midsection. It has a pair of curved horns which it uses in charging attacks and it can bring down rubble to try burying its opponents alive. Its name is a play on "The Hexagon", where it resides, and the word "goon".
Hideous hulk that once prowled the passage of the Hexagon, preying on travellers. The earth shakes with its every step. Its diet consists mainly of rocks and boulders, and it loves dark places, so the Hexagon made a marvellous home.
