Treasure chest

Treasure Chests (often referred to as Treasure Boxes) are scattered throughout Mushroom World in many different games. Some hold the most mundane of items while others hold unique items needed to complete a quest.

Treasure Chests first appeared in Donkey Kong Country 2: Diddy's Kong Quest, where they were used to throw at enemies. After hitting an enemy, they would break apart and leave an item, such as a Banana Bunch. Treasure chests also appeared in Jolly Roger Bay and Dire, Dire Docks in Super Mario 64 and its remake, Super Mario 64 DS. If a character touched one of these Treasure Chests in the wrong order, he would be shocked and stunned, but if he touched them in the correct order, he may have gained either Bubbles, a Power Star, or have caused water to drain.

In Wario World, each Treasure Chest contains one of Wario's sixty-four treasures. However, each Treasure Chest is linked to a Treasure Button, which must be activated before the treasure can be collected.

In Super Mario RPG: Legend of the Seven Stars, Treasure Chests hover in the air (just like ? Blocks), and must be hit from below. They can contain coins, items, mushrooms, weapons, and even monsters. These monsters are Pandorite, Hidon, Box Boy and Chester. A golden Treasure Chest is in the last area of Bowser's Castle, which contains an infinite amount of Gold Coins. Surprise Boxes, special invisible Treasure Boxes, also appear in the game.

In the Paper Mario series, Mario could find many Treasure chests on his adventures. They contain either Badges or Keys. In very big Treasure Chests, there are weapon upgrades such as Super Boots or Ultra Hammer. There is another type of Treasure Chest called the Black Chest. These chests contain demons which "curse" Mario with various abilities. Several Boos also appear in Treasure Chests in Boo's Mansion and Creepy Steeple. In Super Paper Mario, Pixls also appear in chests.

In Super Mario Galaxy and its sequel, treasure chests appear as either optional items or something needed to progress through the level, such as a Launch Star. They can be opened by throwing shells at them. Shiny Treasure Chests also appeared in that game. Some chests contained Coins, Star Bits, a Launch Star, a 1-Up Mushroom, or just a bubble. One chest in the Bigmouth Galaxy is a Golden Treasure Chest that can only be opened by a Golden Shell. Many chests can be found underwater.

Treasure Chests also appeared in Wario Land: Shake It!. Wario could open them by performing a dash attack. In the level Boogie Mansion, however, the chests were living creatures, which would eat Wario if he got too close to them. Wario had to use an explosive to get the treasure inside those living chests.

In Mario & Luigi: Bowser's Inside Story, treasure chest-like enemies known as Trashures and Dark Trashures appear in certain levels. When they are low on HP their locks will fall off and they will open their mouths, revealing their treasure, Bowser can then inhale their gold coins by using the Vacuum command.

In Luigi's Mansion, treasure chests appear after Luigi beats the ghost(s) in a room. Blue Treasure Chests contain Keys. Green ones contain many Coins, Bills and possibly Gold Bars. If the green-hatted plumber defeats an optional gallery ghost, he will also receive a green chest with a Silver Diamond inside, among other treasures. Red Treasure Chests contain Mario's dropped Items that need to be taken to Madame Clairvoya. There are many red Treasure Chests in the Hidden and Sealed Rooms as well, though many in the former contain ghosts. There are also gold chests revealed after defeating bosses, which contain area Keys.
