Hmm...i'm a farmer walking in my field. Lalalaaaa...ho! a stone! (pick it up) Yeah! Could be handy......Why is there a hole in my field? Who cares! I'll jump in it! HO! Bat. HO! Jelly monsters. HO! Jumping stone. HO! Big stone with moss on its head? Where the hell am I?
Any logical person would jump in a cave full of monsters just for the heck of it...right?
