Moleworm

The Moleworm is an animal found in the Reign of Giants DLC. Moleworms live underground in a hole called a burrow, and move around underground similar to the Depths Worm. They will seek out and collect minerals left on the ground, as well as any Gears, Heat Stones, Ashes, or Ice they come across. After collecting 2 stacks of items, they will return to their burrow to drop them off.

When the player digs up their burrow with a Shovel, the burrow is destroyed and a couple minerals will spawn, as well as any item that a Moleworm has stashed inside it. The homeless Moleworm will then wander off and dig itself a new home somewhere. If the player has a Hammer, the Moleworm can be knocked out when it surfaces, allowing the player to pick it up.

Since "A Feet of Strength" update, they will slowly starve in the inventory when picked up.

Tips

 * Minerals can be used as a bait to catch moleworms. Without the bait, moleworms emerge from the ground only occasionally.
 * Moleworms cannot be trapped. In addition, they activate traps that have been laid down.

Trivia

 * The ability to knock a Mole out with a Hammer is a reference to the popular game, Whac-A-Mole.
 * The Moleworm's appearance is based on the star-nosed mole.
 * Moleworm used to make the same sound as a murdered Rabbit when killed in the inventory.
 * Moleworms can steal Gunpowder left on the ground, which results in an explosion.
 * Moleworms vomited up by a Catcoon (wild or tamed) cannot create a burrow. It is unknown if this is implemented to prevent infinite moleworms or simply a bug.
