It appears that huons are walking on hind legs when on slopes. Frontlegs generally suspended in the air. Kinda scary when they advance towards you but I suspect the game is not positioning the mob correctly on land that isn't flat. So the mobs are horizontal regardless of the terrain.
This is the very reason why Behemoths never entered the game...2003 And why eomons looks like horny meatloafs when hunted on the edges of the Echinda crater
LoL...could this have to do with how their personal bubble stick out around them? ...because some times if you are within a foot and a half of them, you are touch them or an invisible part of them.
Hmm Exarosaurs and some other Calypso mobs are fixed so they lean to the side when walking in slopes... looks weirdest when they lean over 40 degrees towards the slope
