 * In Default difficulty, the skeleton horseman is the rarest powerful mob in the game, only spawning in the fossil area in the Cacti Canyon.
 * The first skeleton horse that heroes find has a rider, unlike in the base game.
 * It's rare to find skeleton horsemen going solo.
 * The Skeleton Horse model is different to the one the main game uses, since all Horse models were changed in recent versions. Due to the model being different, the texture is outdated.
