They aren't exactly like Gorons since they are not really humanoid like, using smaller or weaker creatures is used throughout many games and can't possibly cause trouble (Super Mario RPG, Dungeon Keeper and a few more), rock eating can't be copyright since it's also used in numerous things (Both books and games). So I think that the Zulites can safely be said not to cause copyright infringement.
