Loot Leprechaun

The Loot Leprechaun is a secret enemy that spawns in the Rotgut Distillery area of the Mad Moxxi and the Wedding Day Massacre Headhunter Pack for Borderlands 2. Unlike other traditional enemies, the Loot Leprechaun cannot be killed with weapons. However, hitting him with melee abilities releases several drops of loot.

Strategy
The Loot Leprechaun can be found after completion of the A Match Made on Pandora mission. He spawns in the Hodunk Holler area of Rotgut Distillery from a small cave near where the main road heads into the mountain tunnel. This is to the left of the entrance to the Moedown Motel area. The Loot Leprechaun has a high spawn chance, but not 100%.

The Loot Leprechaun moves very quickly, much faster than other enemies. He can easily be found by the rainbow trail that he leaves in his wake. He occasionally stops, making it easier to approach him. Sometimes he can be stopped if a player stands in front of him. Shooting him will result in no damage, even if he is hit with Slag damage. However, hitting him with a melee ability releases his loot. He can be hit several times before disappearing.

If, however, players do not make him disappear by hitting him, he will continue to run around the area. His path is generally chaotic, but he works towards one of two caves. Upon reaching one of these caves he will disappear. Hitting the Leprechaun with melee rewards Eridium bricks, ammo, and money.
 * 1) The first cave is near the entrance to Hodunk Holler when coming from the chapel. Before reaching the pond there is a small cave on the right, somewhat close to the house where Nathanial Lynn Zaford is visited during Learning to Love.
 * 2) The second cave is on the other side of the pond off of the main road just before the gate leading to Zaford's Rotgut Distillery. This cave is also on the right.

The Leprechaun can respawn, but his chance of respawning is less likely.
