Treasure Chest

Treasure chests contain items.

Kirby Super Star and Kirby Super Star Ultra
In the sub-game Great Cave Offensive, players are encouraged to collect treasure chests that contain items. These treasures do not do anything but better ensure the player get 100% completion.

Kirby & the Amazing Mirror
In Kirby & the Amazing Mirror, treasure hunting is again featured. This time, the treasures are of more value- from food and 1ups, to collectible items (Health bar enlargements, Level Maps, the game's sound test (collected through individual treasures), and spray paint cans that change Kirby's color if you don't feel like pink all the time).

Kirby Squeak Squad
In Kirby Squeak Squad, treasure hunting gains a new catch: Kirby must collect the treasures in his belly and go to the goal door to open them. There are two types of chests: the small red ones and the big golden ones. Squeak Squad members will appear on certain circumstances to steal any chest they can find, grab, and take to a hideout. To make sure Kirby gets the chest, he must fight them until they get knocked out, and then take it. If a Squeak takes it to a hideout, Kirby must hurry before they bar up the entrance door. On another note, a special kind of Waddle Dee known as the Golden Waddle Dee carry treasure chests. They run around fast- and Kirby must inhale or destroy one (but not let them get away!) in order to get that chest.

If Kirby neglects a treasure chest or fails to obtain one, he must replay the stage to get it.

In Kirby Squeak Squad, some of the same basic treasures from Kirby & the Amazing Mirror return, along with some new ones (Copy Scrolls, Ghost Medal pieces, Copy Palette styles (i.e. the player can decorate Kirby's stomach), keys to unlock secret stages, jigsaw puzzle pieces that will create four different pictures, and pieces of a map for a secret place where Kirby can access all abilities he has unlocked). Most of them are just for fun, but some treasures are actually mandatory- when Kirby defeats a boss for the first time, a chest will appear that give items called Boss Badges (They look more like trophies, though). In levels 2-6, there are certain items in treasure chests called Star Seals. There is one in every level and they are always in big treasure chests; the radiation from the star seal causes the chest to glow, thus making it easier to spot. Kirby must obtain all the seals and finish Ice Island to use the star seals and grant access to Secret Sea, the area where Meta Knight's ship long ago.
