There’s no bottom, no end. It grows faster than I can shrink it. If you were to stand on the ground directly next to it (this is impossible, since we’ve established that there’s no bottom), and fire an arrow at its peak, the arrow would surely miss the top. Not because of the height, no; he gravitational pull of the mass would be enough to draw the arrow into its mouth. Yes, it has a mouth. It chews up the arrow, and spits out an arrow skeleton. Nom nom nom nom.
