The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode in Terraria. It is used to summon the Duke Fishron boss. In order to use it as bait, it must be caught with a Bug Net or Golden Bug Net and used with a fishing pole in an Ocean biome. It only spawns in the Cavern layer and below, so it will not appear in surface Glowing Mushroom biomes. 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.

The Truffle Worm spawns in the underground Glowing Mushroom biome during Hardmode
The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode. It is used to summon the Duke Fishron boss. To catch it, you will need a Bug Net and it can be used as bait with a fishing pole in an Ocean biome.
Truffle Worms only spawn in the Cavern layer and below, so they will not appear in surface Glowing Mushroom biomes. They are considered difficult to catch due to their burrowing ability, which makes them hasty runners. They are also tricky to spot. To increase the chances of finding Truffle Worms, you can convert a large section of the Underground Jungle into an Underground Glowing Mushroom biome using the Clentaminator with Dark Blue Solution. Alternatively, you can use Mushroom Grass Seeds on plain Mud Blocks, though this is a slower process.
Another strategy is to repeatedly move away from and back to a Glowing Mushroom biome, causing new enemies to spawn and potentially a Truffle Worm. Using Teleporters or the Portal Gun can create an infinite falling loop, causing other enemies to despawn and increasing the chances for a Truffle Worm to spawn. Building a multi-level farm can also be useful for farming both Truffle Worms and Glowing Mushrooms.
Water Candles and/or Battle Potions can increase the spawn rate of Truffle Worms. However, this also increases the likelihood of the worms being killed by additional enemies, as well as posing a hazard to the player.

It is a rare critter that can be used to summon the Duke Fishron boss
The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode. It is used to summon the Duke Fishron boss.
To catch the Truffle Worm, you need to venture into the underground Glowing Mushroom biome with a Bug Net, a Lavaproof Bug Net, or a Golden Bug Net. The Truffle Worm is more difficult to catch than other critters because it burrows and runs away quickly when a player comes close. Using an invisibility potion can help as it makes the Truffle Worm wait longer before running away. However, taking any damage will cancel the invisibility buff.
Once caught, the Truffle Worm can be used as bait to summon the Duke Fishron boss. To do this, use the Truffle Worm with a fishing pole in an Ocean biome. The Truffle Worm must be the first bait used, and once the bobber bobs, reeling in the line will spawn Duke Fishron.
The Truffle Worm is an important item in the game as it is one of the few items that can be used to summon the Duke Fishron boss. It is also interesting to note that the combination of truffle and worm represented by the Truffle Worm ties in with the combined pig-and-fish-like nature of Duke Fishron.

It can be caught using a Bug Net and used as bait with a fishing pole in an Ocean biome
The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode. It is used to summon the Duke Fishron boss. In order to use it as bait, it must first be caught with a Bug Net.
The Truffle Worm is more difficult to catch than other critters because it burrows and runs away quickly when a player comes too close. It can be caught even while burrowing. If the worm is in a small pit, a player can jump up directly under it and swing their Bug Net to catch it as it tries to burrow downward. A Rod of Discord can make catching the Truffle Worm easier by facilitating getting near it. A Golden Bug Net, which has a longer reach and swings faster than a regular Bug Net, can also make the catch easier.
Once caught, the Truffle Worm can be used as bait with a fishing pole in an Ocean biome to summon the Duke Fishron boss. When used as bait in any other biome, the bobber will simply sit in the water indefinitely. It is important to note that the Truffle Worm will always be consumed upon summoning Duke Fishron.

Water Candles and/or Battle Potions increase the spawn rate of the Truffle Worm
The Truffle Worm is a rare critter that spawns in the underground Glowing Mushroom biome during Hardmode. It is used to summon the Duke Fishron boss. It is more difficult to catch than other critters due to its burrowing nature.
Water Candles and Battle Potions can increase the spawn rate of the Truffle Worm. However, they will also increase the likelihood of the worm being killed by additional enemies. A multi-level farm is useful for both Truffle Worms and Glowing Mushrooms. Each existing enemy may reduce the spawn rate of the next, so getting rid of excess enemies will give the Truffle Worm more opportunities to spawn.
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 is to use Mushroom Grass Seeds on plain Mud Blocks. Another simple 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.
Using a Lifeform Analyzer can help announce the presence of the Truffle Worm. Invisibility Potions can also help as they make the Truffle Worm wait longer before running away. However, taking any damage will cancel the invisibility buff.

This can be done using the Clentaminator with Dark Blue Solution. A multi-level farm is useful for farming both Truffle Worms and Glowing Mushrooms. This is because the Truffle Worm is not considered a critter, and 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, so getting rid of excess enemies will give the Truffle Worm more opportunities to spawn.
Another way to increase the spawn rate of Truffle Worms is to use Water Candles and/or Battle Potions. However, this will also increase the likelihood of the Truffle Worm being killed by additional enemies. A simple but slow way to farm Truffle Worms is to move away from and back to a Glowing Mushroom biome repeatedly, causing new enemies to spawn and potentially a Truffle Worm. Teleporters or the Portal Gun can be used to make an infinite falling loop.
Truffle Worms can be difficult to catch as they tend to burrow and run away quickly when a player comes too close. Using an invisibility potion can help as it makes the Truffle Worm wait longer before running away. However, taking any damage will cancel the invisibility buff. Once caught, the Truffle Worm can be crafted into animated decorative furniture, such as a Truffle Worm Cage.
