I think maybe instead of mammoth, you used elephants, more fitting, maybe you could have some people controlling them, like they really do in the desert, so men to kill too? so it'd be a hunting ground for people who need to level up? as for dragons, it could be like a loch ness type thing...wings can be used to ''fly'' through water...so it's not as daft as it sounds, though no rewards? seems abit meh...wouldn't bother with it. The thought is there, just not enough detail. though it did make me laugh!! :)
