The Truffle is a hard mode NPC and will only show up once you have constructed a house in an above-ground mushroom biome with Mushroom Grass Seeds, or by using the Clentaminator in a Jungle. If you want to do this but don't want to take up a lot of surface space, a good way to do it is to build a skybridge of mud off of a Floating island, plant Mushroom Grass Seeds, and then wait. (Note that the skybridge must be 2 mud blocks thick, and that the house must meet all of the other normal NPC house requirements.)
If you are having trouble with getting Truffle to move in, it may help to construct the house purely out of Glowing Mushroom materials (Walls, doors, etc.). Also leaving the house with no floor and instead building it straight onto the grass of the Glowing Mushroom Biome might also help.
