Kirby's Dream Land 3

Boss battle:
Defeat the last Boss to enable the "B" selection on the options screen. Choose this option to begin a battle with all six Bosses in order, with one life, and no chance to heal.

Graphics test:
Complete 100% of the game to enable the "?" selection on the options screen. Choose this option to view all the introduction to the game and all worlds and the various endings.

Jumping mini-game:
Complete the "M" option mini-game to enable the "J" selection on the options screen. Choose this option to begin a jumping mini-game.

Regain health:
Summon your assistant, then assimilate him again to regain a small amount of energy.

Hint: Fun Bones level:
After completing lands 1 to 4, go opening menu and select the game that you have reached land 5. Select "Options" and then select the "M" instead of the sound check (the small music note). This will take you to a little game center where you can play each Bones game in order.

Hint: Defeating Boboo:
To defeat Boboo, the fireball mini-Boss, get the rock ability and chuchu hit him once to take away half his health. Then, spin again. This is faster than taking the rock things he creates when he rams the wall and spitting them back at him. Note: This does not work against the Boss Butch because you do not get an ability in that mini-game.

Hint: Hidden doors:
When you reach a dark area, use Kine the fish and use the powers of electricity to brighten the area. Some stages will have secret doors revealed.

Hint: Two players:
Normally you would press A on the controller one when you have a power to make a helper. To play with two players, press A on controller two. Instead of "CP" appearing above your helper, it will read "2P". Alternately, when you already have a CPU helper, press any button on controller two. Their designation will change from "CP" to "2P". It is much easier to complete the game when you have two players.

In the Ice Land stage 2, the Metroids and Samus will both appear.
