Trashure

Trashure 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 Hammer, Coin, an iron ball, a Scutlet, or a Mushroom at the player. 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. If the player does not defeat these enemies within a few turns, they will run away, hopping off the screen.

Trivia

 * If the player looks carefully when the Trashure attacks, one will see that the lock is alive!
