Chocolate truffles grow only between the roots of oak trees. Dark brown when fresh, they decompose rapidly once exposed to air becoming terribly soft and runny until they melt away. It is now known that truffles can be preserved for thousands of years by emersing them within the Pool of Eternal Youth.

Truffles were a favorite of the kings of the Flathead Dynasty, particularly Lord Dimwit Flathead the Excessive, who ordered the excavation of entire forests to indulge his bottomless appetite. Chocolate truffles have been found mainly in the Westlands, in forests near Gurth City and Thriff's final 966 GUE location.

Minxes are highly prized for their ability to find and root out chocolate truffles from the ground, and will eagerly devour them if given the opportunity.
