Truffle

A truffle is the fruiting body of an underground mushroom; spore dispersal is accomplished through fungivores, animals that eat fungi. Almost all truffles are ectomycorrhizal and are therefore usually found in close association with trees. According to Brainy Smurf, humans use pigs to sniff out truffles whenever they went looking for them.

Truffles are used by the Smurfs in various forms, which include food and beauty care. In the episode "A Mere Truffle", Tracker was sent out into the forest to search for truffles when he ran into Azrael, causing him to lose the truffles he has collected. The Smurfs did not like that Tracker only managed to bring home one truffle, so at Papa Smurf's suggestion Tracker brought a group of Smurfs out into the forest to look for more truffles, only to get hit in the head with a rock and lose his memory. His fellow Smurfs got captured by a group of Truffle Trolls who saw that they were stealing their truffles and thus were sent to the isle on the Lake Of Doom where they would have to deal with The Thing With No Name, a creature that the trolls constantly fed truffles to. Papa Smurf's group of Smurfs rescued the ones stranded on the island by feeding the thing with their bag of truffles, eventually gaining its help when they fled across the lake on boats from the Truffle Trolls, with the thing crushing the trolls' boat and sending the Smurfs through an underwater passage which helped them escape from the cave.

Truffles are also one of Empath Smurf's favorite foods in the EMPATH: The Luckiest Smurf story series.
