An iceberry is a type of berry that usually grows in the Smurf Forest during winter. The berries have a whitish-blue tint and taste like a very minty blueberry.
In the EMPATH: The Luckiest Smurf story series, iceberries are used by Greedy, Biscotti, Gelato, and Tapper in the preparations of various Smurf foods and drinks. Papa Smurf also uses iceberries for his experiments and remedies. The iceberry leaves are used for smoking herbs in cigarettes.
