The Liquid of Petrifaction is a magic potion that turns everything it touches into solid marble. It was invented by Dr. Pipt who once used it to turn two attacking kalidahs into lawn statuary.

In an unfortunate accident, Unc Nunkie and Dame Margolotte were petrified by the Liquid, so Ojo set out on a long search for the ingredients of the antidote: A Six-leaved Clover, the left wing of a yellow butterfly, a gill of water from a dark well, three hairs from the tip of a Woozy's tail, and a drop of oil from a live man's body.
