Truffle Trolls are a group of trolls that resemble humanoid pigs that appear in the cartoon show episode "A Mere Truffle". They live in a cave inside a mountain at the south end of the forest. They are so named because they go after truffles like pigs, but instead of eating them, which makes them sick, they feed the truffles to a creature that lives in the Lake of Doom inside the cave called "the thing with no name", which only appears in the form of green tentacles.
