Unfortunately, in your haste to transform me into a harmless form, you fail to realize that the exact description of butterfly you have given me is also known as Mothra, IE a massive super pyro butterfly. I lose interest in the hill only because it's currently a massive pyre, and you are too busy using not-flameproof construction materials and also burning to properly claiming it, forcing your retreat.

I then regain interest for no good reason whatsoever, and reclaim my hill.

MY HILL.
