Extra Mode

Extra Mode is a mode that can be unlocked in several games by completing the main game.

Kirby's Dream Land
In this game, Extra Game can appear in the game's menu after beating the main game. When this happens, it tells the player a special button combo to unlock it.

In Extra Game, there are several features that will differentiate itself from the main game:
 * Enemies do twice the damage or are faster, or are replaced by versions that do twice the damage.
 * Bosses may use Gordos as projectiles.

Kirby's Adventure
If the player beats the main game with 100%, they automatically gets this as an option in the menu.

In Extra Mode, Kirby has half as much health. Also, progress through the Extra Game won't be saved.

If Extra Mode is completed, the player is awarded with the Sound Test option in the menu.

Kirby: Nightmare in Dream Land
Extra Game appears in this remake of Kirby's Adventure. Unlike the extra mode in Kirby's Adventure, progress is actually saved. Also, if the game is beaten, the Meta Knightmare sub-game will be obtained, where the player gets to play as Meta Knight in a nonsavable crash course of the game. The hard part is that he only gets three hit-points.

Kirby's Dream Land 3
The Extra Game here is called Super NES MG5, consisting of a complete re-run through all the Heart Star missions by Pitcher Man, Elieel, Caramello, Tamasan, and Chef Kawasaki.

Kirby: Squeak Squad
The Extra Game is timed run to obtain all the treasure chests as fast as possible in one run; the final time is not saved until all the chests have been collected. Like Meta Knightmare in Kirby's Adventure, the player's progress is forfeited should he/she leave the game halfway.

Kirby's Return to Dream Land
Ex Mode is unlocked after beating the main game. Bosses and mid-bosses have "EX" appended to their name, and they gain additional attacks not seen in normal mode. Kirby and co.'s maximum health are reduced to 50% as per tradition. Moving walls in Dimensional portal sequences are faster than before. Other than the previous changes which increase the difficulty, collectibles have more detail or have certain embellishments and decals added to them, and Stone Kirby can only transform into certain forms after normal mode is complete.
