One-Eyed Willie was named one of the first Goonies! Pour hot liquid treasure in his cool black mug and watch his remains morph as a pirate who is guarding his gold and doubloons far below in a booby-trapped cave. The Inferno lay resting in a lagoon hidden for centuries waiting to be found. See his pirate hat and one-eyed patch appear as you dream of the treasure and the temperature changes from cool to hot!
