Hint: Ball ability:
The Ball ability may seem useless at first glance, as it is only a form of moving around a level. However, while Kirby is flashing as a ball, he is invincible and does a ludicrous amount of damage to enemies in his path. This makes it possible to destroy King Dedede in five hits. However, you will be vulnerable momentarily when you hit the ground. Jump into Bosses at such an angle that you will not land "inside" them.

Hint: Laser ability:
Long distances are your friend. If you keep hurting yourself with Ball, give Laser a try. It may be weak on Bosses, but as long as you stay as far away as possible, they cannot harm you. If you want slightly more muscle at the expense of range, try Cutter.

Hint: Parasol ability:
When you suck in an enemy carrying a parasol, swallow it. Jump up high so that you reach the top of the screen and press B(2). Move around with the D-pad, and you will float down gently. This is a good strategy for defeating enemies that cannot jump. Note: Bugzzy, Bonkers, etc. can jump.

Hint: UFO ability:
Hold B button for five to ten seconds, which will make double star (similar to when you suck in two enemies). It will send the star that will eliminate all enemies in its path until the end of the screen.

Hint: Museum trick:
If you you have unlocked all the stages in a level, try to defeat the Boss. Go to the museum and swallow any enemy if you do not have an ability yet. Remember to only jump once; jumping twice will cause Kirby to pop the enemy, then you will have to leave and return again. Go to the Boss level, and when you enter, press Select to throw away the ability. However, try to make it hit The boss. They will get some damage, making it easier to defeat them.

Hint: Defeating the Bomb Brothers:
Use the following trick to defeat the Bomb Brothers at the same time. Stay in the middle with Spark, Frezze, and Neddle and hold B. Note: If they move on different times, this will not work.

Hint: Defeating King DeDeDe:
To defeat King DeDeDe easily, get the Hurricane move and keep going back and forth hitting him. If you keep moving in that way, he probably will not hit you. After defeating King DeDeDe, you have to fight a moon-type thing. To defeat it, stay in the middle on the left side of the screen and only move when necessary. Most of its attacks will miss. Then, use your Starwand and shoot stars at it rapidly.

Go back to level 5 and suck up a bomb then eat it to get its power. Then, fly over the rest to avoid damage. Next, go through the door at the end of the screen. Then use your power on the giant wheel. Then the wheel should charge you. Jump over it and it should fall over and a mini wheel will appear. Suck up the tire (do not eat it), then spit it at the wheel and it should die. Suck up the wheel and eat it to get its power. Then, press Start and select "Exit through a door". Then, fight King DeDeDe and just go back and forth using the wheel. Note: Try pushing B immediately before you hit the side of the screen.

Before going through the Boss door to fight king DeDeDe, go to level 5. Go a little way and inhale the spinning top to become Tornado Kirby. Then, return to the map and challenge king DeDeDe. Keep using the Tornado ability to defeat him. He cannot hurt you as long as you continuously press B.

When you are facing King DeDeDe, you can defeat him easily with five to ten hits using the copy ability High-Jump.

To Defeat King DeDeDe, get Laser Kirby and just blast and jump.

Hint: Defeating the Nightmare Ball and Nightmare Wizard:
When fighting the Nightmare Ball, he follows this order of attacks: two stars, rapidly shoots three stars, then at first he will shoot four stars horizontally only. After he only has one fifth of his life remaining, he will shoot them opposite by twisting them. The most difficult part will be when he shoots crescent moons -- bottom, top, bottom, top, middle is the order. When he is defeated, you will fight the Nightmare Wizard. He will first shoot stars in an up, down, or middle direction, followed by another which is in a more straight pattern. This is a good time for you to attack. He then warps around four or five times, then reveals the tornado behind him (which is a weak spot). You can easily attack him there. He then does two attacks in random order. He will go to a corner where you can the Spinning Tornado behind him and fire stars rapidly, or he will dive at you. When his life is low, he will fly upside down revealing the tornado for about a second -- you must be quick. Repeat this pattern to defeat the main Bosses.

Hint: Defeating Wispy Woods:
Get either Sword/Spark/Fire/Freeze/Ice Kirby, then stay close to him. He will not attack you there. Keep attacking him and he will soon be defeated.

Note: You can also use Needle.

Hint: Completing Boss Endurance:

Wispy Woods: Avoid air puffs and shoot dropped apples.
Paint Roller: Inhale the cloud and use Shock Kirby.
Mr. Sun and Mr. Bright: Use Shock ability from last battle.
Kracko: Race to top as High Jump Kirby and jump at Boss.
Heavy Mole: Inhale missile and hit Boss with hammer.
Meta-Night: Avoid long range attack; jump and hit.
King DeDeDe: When he jumps, hit him with Sword Spin.

Hint: Level 7-2: Extra lives:
In level 7-2 (Rainbow Resort stage 2) in the first room, fly onto the ledge exactly over the door. Fly straight up to the top of the screen and you should see a black rectangle covered in vertical lines. Fly in front of it and press Up as if it was a door (and it is). Once inside, you should have skipped a some Bosses and be at Bonkers the monkey. After defeating the Fire Lion, you will enter a room with five extra lives.

Hint: Easy lives:
If you need a lot of lives for a Boss battle go to "previous" doors and look for sub-games in other levels. The ranks are as follows. If you do well, you should get about 18 or 19 lives. First place: 3 lives
Second place: 2 lives
Third place: 1 life
Fourth place: nothing
