The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode. It is solely used as bait to summon the Duke Fishron boss. It only spawns in the Underground layer and below, so it will not appear in surface Glowing Mushroom biomes.

On the  Desktop version,  Console version, and  Mobile version, Truffle Worms do not take damage from enemies.

The Truffle Worm can be caught with any Bug Net, however it is more difficult to catch than other critters, as it burrows away when a player comes too close. It must be approached quickly in order to successfully catch it. After being caught, it can be carried around in the inventory and released later, or crafted into animated decorative furniture (Truffle Worm Cage). Once crafted, the Truffle Worm cannot be released again.

Despite having a bait power of 666%, the Truffle Worm cannot be used for ordinary fishing, and can only be used to summon Duke Fishron by fishing in the Ocean biome. When attempting to use it as bait elsewhere, the bobber will simply sit in the water indefinitely.

The Truffle Worm will always be consumed upon summoning Duke Fishron. Items that reduce the chance of bait consumption such as the Tackle Box or its upgrades will have no effect.

It is one of the few entities that can be detected by the Lifeform Analyzer(Desktop, Console and Mobile versions) or its upgrades.

Notes

• When the Truffle Worm is used for fishing, the Fisherman's Pocket Guide(Desktop, Console and Mobile versions) (and its upgrades) will display "Warning!" instead of Fishing Power.
• The Truffle Worm is internally considered an enemy rather than a critter, despite not posing any threat.
  • (Desktop, Console and Mobile versions) They do not take damage from enemies.
  • However, the Hunter Potion will highlight it in green, like other critters, instead of red.
  • Furthermore, the Guide to Critter Companionship(Desktop, Console and Mobile versions) will prevent the player from killing it accidentally.
• Truffle Worms follow the Worm AI even in their passive state on 3DS.
• 100 tiles of Mushroom blocks are not necessary for Truffle Worms to spawn. Mushroom enemies and Truffle Worms will spawn wherever there is Mushroom grass, without requiring that the area is actually considered a Glowing Mushroom biome.
  • On Mushroom grass, each enemy spawn has a 2/3 chance of being a mushroom-themed enemy or critter. Each time this happens, there is a 1/7 chance (1/5 as of 1.3.0.1(Desktop, Console and Mobile versions)) that the mushroom-themed character is a Truffle Worm. Considering the maximum spawn rate (1/60 per tick), the maximum expected Truffle Worm spawns is 343 per hour (2/3*1/7*3600) (480 as of 1.3.0.1(Desktop, Console and Mobile versions)).

Tips

Using the Underground Jungle to farm Truffle Worms (having four at the same time was just lucky).

A multi-level farm is useful for both Truffle Worms and Glowing Mushrooms.

This is another multi-level farm, also useful for Truffle Worms and Glowing Mushrooms.

Spawning

• Since the Truffle Worm is not considered a critter, NPCs should not be used as a means to increase the proportion of critters in the total number of creatures spawned.
  • Each existing enemy may reduce the spawn rate of the next. Getting rid of excess enemies will give the Truffle Worm more opportunities to spawn.
  • Water Candles and/or Battle Potions will increase its spawn rate.
• One way to increase the chances of finding Truffle Worms is to convert a large section of the Underground Jungle into an Underground Glowing Mushroom biome, using the Clentaminator with Dark Blue Solution. A slower alternative would be to use Mushroom Grass Seeds on plain mud blocks.
• A simple (but perhaps slow) way to farm them is to move away from and back to a Glowing Mushroom biome repeatedly, causing new enemies to spawn and potentially a Truffle Worm.
  • The Portal Gun(Desktop, Console and Mobile versions) can be used to make an infinite falling loop. If it is high enough, going in can cause other enemies to despawn, allowing the Truffle Worm to have more chances to spawn.

Catching

• Truffle Worms will burrow themselves (eventually despawning) if the player is near them for about 1 second, so the use of a speed-enhancing item is suggested. Hooks, wings, or Lightning Boots grant speed improvements; Tabi, Master Ninja Gear, a full set of Crystal Assassin armor(Desktop, Console and Mobile versions), or Shield of Cthulhu(Desktop, Console and Mobile versions) (though this item deals damage and thus may be less suitable) allow dashing.
  • If a Truffle Worm is let free by a player, it will also burrow, and despawn almost immediately if approached or stood near to for more than a few seconds.
  • It should be noted that, if the Truffle Worm burrows offscreen, it will despawn as soon as it is offscreen. If it falls, however, like a normal enemy and the same way a worm would, it will follow normal NPC despawning rules, and can be followed for more distance.
• The Truffle Worm can be caught even while burrowing. If the Truffle Worm is in a small pit where it is impossible or very difficult to catch from above, and there is a cave below it, a player can jump up directly under it and swing the Bug Net to catch it as it tries to burrow downward.
• Summoned minions do not directly target the Truffle Worm but can inadvertently kill it.
• A Rod of Discord makes catching Truffle Worms easier, since it greatly facilitates getting near them.
• A Golden Bug Net(Desktop, Console and Mobile versions) has a longer reach and swings faster than a regular Bug Net, making the catch easier.
• Since the Lifeform Analyzer can announce the presence of a Truffle Worm, it is highly recommended to carry it.
  • Furthermore, since enemies despawn further than the Lifeform Analyzer's reach, one can estimate the location of the Truffle Worm and accelerate the process of hunting it.

Trivia

• The number 666 in the Truffle Worm's "666% bait power" is a reference to the number of the beast, commonly associated with Satan. This alludes to its ability to spawn Duke Fishron.
• The combination of truffle and worm represented by the Truffle Worm ties in with the combined pig-and-fish-like nature of Duke Fishron.
  • Traditionally, pigs have been utilized for the extraction of edible truffles, a highly prized food.
  • This is also referenced by the Truffle's quote "You haven't seen any pigs around here have you? My brother lost his leg to one.", as well as how the Pigron and Cute Fishron mounts' summoning items are all Truffles.
• The Windy Balloon(Desktop, Console and Mobile versions), Lunatic Devotee, Truffle Worm, and Prismatic Lacewing(Desktop, Console and Mobile versions) are the only entities classified as an "enemy" that otherwise deal absolutely no damage to the player.

• The Bestiary entry for the Truffle Worm: "An extremely rare, difficult to catch glowworm. A specific, powerful sea creature is insatiably attracted to these."
