Trashure

Trashures are brown treasure chests that appear in Mario & Luigi: Bowser's Inside Story. They attack by opening their bodies, and having the lock on them throw either a Scutlet, a Hammer, an iron ball, a Coin or a Mushroom at the player. They will throw three to five random items. If countered, the object will fall back on to the Trashure, damaging it if the object thrown was one of the first three items, and healing it if it was a Mushroom.

If the lock is significantly damaged, it will eventually fall off, which will make the chest open, exposing the treasure to Bowser's Vacuum command, which will suck the coins out of the Trashure, defeating it at the same time. If the player does not defeat these enemies within a few turns, they will run away, hopping off the screen. If they run away, the player does not earn any experience points for battling it. Mario and Luigi, having no access to the Vacuum command, have no choice but to simply keep attacking it until it is defeated.

They have a stronger variant, the Dark Trashure.
