Treasure Goblin (mob)

Treasure Goblins are small, mischievous creatures that can spawn throughout the Broken Isles as well as at the end of any Broken Isles dungeon during the course of the Diablo's 20th Anniversary world event. If attacked, they will attempt to run away, and if not killed in time they will open an Escape Portal and despawn. If they are successfully killed, they will drop various items as well as cause another portal labeled "The Secret Cow Level" to open nearby. The latter can be used to teleport to a phased version of the Yorgen Farmstead in Duskwood inhabited by Diabolic Bovines, Diabolic Tauren and the Cow King.

Trivia

 * Just like the companion pet of the same name, the Treasure Goblin is a reference to the creatures of the same name found in Diablo III. Diablo III's Treasure Goblins are creatures rarely found in dungeons that are initially stationary, but will start to run away if attacked and drop increasingly better loot with each hit. If they go several seconds without being attacked, the Treasure Goblin will escape through a portal and disappear. It was later revealed that Treasure Goblins serve a demon lord known as Greed and that their escape portals actually lead to Greed's domain.
 * After being killed, they exploded in a shower of gold coins, another reference to the Diablo franchise.
