Dark Trashures are another treasure type of enemies found in Princess Peach's castle when Fawful fawfulized it. Like their more colorful counterparts, they will chuck cannonballs, golden hammers, coins, and Mushrooms that heal 100 HP. After a considerable amount of damage done, they will open up, revealing their coins. Unlike the regular Trashures, who release (10 coins) at max, these guys can release (100 coins). In the original game, while Mario and Luigi cannot normally fight Dark Trashures, it is possible for them to battle one with cheats enabled. Most of its attacks function normally, with the objects being thrown at either of the Mario Bros., and they can be dodged by jumping; however, the cannonball is thrown at such a rapid speed that it is very difficult to predict and dodge beforehand.
