I was miserable for weeks in this cave until I spoke with an expert speleologist. "Oh, just do the bossanova," he said, "The acoustics of a cave are perfect for the bossanova."
Then an alien walked up and challenged my speleologist friend to a duel. He accepted, and the alien immediately shot him with some kind of science-fiction-lookin' ray gun.
The speleologist split in into two children when he was hit with the ray, and that was that.
