The problem here is how world loading works. As big as they are quite often these creatures are outside the players chunk load radius so the "look" of terrain is just a wholly permiable mesh(like a curtian) to give the appearance of a wall until the player is close enough for it to actually spawn the terrain.

This is also why you sometimes see creatures appear out of nowhere as they go flying off into the distance from being shot out by chunk load
