Defeat Goomba King easy
Start by making Mario hit the tree next to him to defeat the Goomba Bros. and damage Goomba King. Make Goombario use Tattle on Goomba King. After Goomba King attacks Mario use a Fireflower on him and make Goombario attack. After Goomba King attacks Mario again, just attack and you should beat him with 8 or 13 HP left!

Easy Star Points
In Flower Fields (Chapter 6), there are a lot of enemies called Crazee Dayzees. But in a certain spot you can find an Amazee Dayzee which gives around 40 starpoints, and you can fight it as many times as you want! When you get in flower fields, go to the bottom right path. Give the flower a yellow berry to open the gate if you havn't yet. Go across the platforms to a small patch of flowers next to a tree. There will be two crazee dayzees in the patch. But there is a chance that one of them will be shining gold. Keep leaving the area and coming back until you see a gold one, and attack it. It is an amazee dayzy. The problem with these guys is they run 99% of the time when they can, and have 20 HP! There is a SLIGHT chance they will attack (for 20 damage, watch out!). So the trick is to kill them in just 1 turn. This is very difficult because of the high HP, and they hardly ever get dizzy or asleep. But I have a strategy for killing it WITHOUT USING ANY FP! It requires the Dizzy Attack Badge, an Ultra Ranked Watt, and good timing (If you miss one of the action commands, the flower will get away!). (optional) The mega jump/smash badge, for say if watt misses an action command on the first turn, (and does 1 instead of 5) you would use that to make up for it next turn because the megas increase the attack by +4. Now find an amazee dayzee, but dont attack it yet. First, I reccomend you kill the crazee dayzee, so it doesnt bother you. Then, SPIN into the amazee dazee. Because of the dizzy attack badge, it will be out for 1 turn automatically, giving you 2 turns to attack! Use hammer and you will do 5 damage (it has one armor). Then use watts electro dash and you will do 5 because the attack goes through defence. The dazee will get up, but loses her turn. Repeat the attacks and you will win! After it dies, you have to leave flower fields completely before it comes back.

Infinite items from trees
Once you have received a hammer, use it to hit trees. The tree by where you begin gives you an endless supply of acorns that revive your FP by 3. You must go somewhere else to get another acorn, though. You can also get coins, star pieces, and a weird doll as well.

Infinite hearts
Find the split on Pleasant Path where one direction leads to the Koopa Bros. Fortress and the other leads to Koopa Village. Keep running around the striped pole next to the sign to get hearts.

Special spells
Go to the alley right next to Toad's house in Dry Dry Outpost. Jump forward over the left box and the camera will swing around to reveal a hidden area. Talk to Merlee to learn about her special spells. Depending on how much money you spend, she will help you during and after battles. The spells do wear off after a certain amount of time, but until then, it provides you with additional attack power during some battles and more coins after battles.

Hidden playroom
Go south in Toad Town until you get to the area with the Li'l Oink Farm. Go left immediately after you enter this area (there is a narrow passageway that's not fenced off). Hit the tree with your hammer and a pipe will appear on the right. You can now enter the playroom, but need either a Silver and/or Gold card to play the games.

Classic Mario music
Go to the third house in Koopa Village (a Koopa is sunning himself inside). Stand in front of the radio and press A to switch between stations. Listen to the Golden Oldies station to hear classic Mario theme music.

Tips on the boss battles.
Section I: For Battling:
1. Koopa Bros.
Use your Jump with a Power Plus (if you can get one) and a Multi-Bounce Badge. They will increase attack power and flip the turtles on their backs. When they are flipped over, whatever one you attck will stay down until defeat. For the Beginning with bowser, just use your jump and when he attacks press "A" to reduce damage.

2. Tutankoopa
Use Parakarry's Shell Shot to hit him while he is on the platform and Mario should have a Multi-Bounce, Power Plus, and another Power Plus you can get from the castle. This will do about 3-4 on the first hit and 3 on the second, 2 on the thirs, then 1 damage every hit after that. When he uses the magic rock spell press "A" before he hits you to reduce damage. You will lose your partner but by now you should have him at 15-12 HP left. When he summons Iron Chomp, use your Jump if that's your fancy but i recommend using the Hammer since it is powered up.

3a. Tubba Blubba's Heart
This is your first 2-part battle. Use Bow as your partner and Multi-Bounce the heart. When he starts to glow use Bow's "Hide" attack so you don't lose 12 HP. Really, this battle is just a walk in the park, while holding a hammer and pounding someone's heart senseless, lol.
3b. Tubba Blubba
This guy only has 10 HP! Just Hammer him and block his attacks and he'll be defeated.

4. General Guy's Army
This Battle starts with 15 guys at 1 HP each. For example: if you jump and do 3 damage 3 guys will die. However many there are left is how much damage you'll take. For another example: if there is 5 left at the end of your turn you'll take 5 damage. To end this part kill them al or if one is left he'll scamper away. The second part tests you against Stilt Guys. There are 2 with 10 HP each. Just jump (the best solution) with a multi-bounce to defeat them. When they are gone you have the last part of the army to deal with. These are like the Stilt Guys except with no stilts. They have about 15 HP each i think.....or it is 10? Doesn't matter, this'll be a very annoying battle to fight. Just use your best Hammer Techniques to defeat them. Eventually you will have to deal with the General Himself.....
4b. General Guy and his Tank
Now you probably have about 25 health left. When fighting him use Watt. First you HAVE TO GET RID OF THE BULB ON HIS TANK. IF YOU DON'T HE'LL ZAP YOU CAUSING 8 DAMAGE. After you deal with the Bulb, Hammer his Tank and Zap it with Watt. When you zap him you'll discover that he's weak to electricity. He only has 30 HP which will disappear very fast if you do the following: Use Star Storm then a zap from Watt. Then, heal yourself and Zap him with Watt. Eventually he will fall.

5a. Lava Pirahna
This is the second most annoying battle in the game. Equip Ice Power Badge and extinguish those other little 2 Pirahna Plants with your jump. Then aim all your power at the Main Enemy: Fire Pirahna. The power of Ice will do about 6 damage and hit him with Parakarry's Shell Shot. He will die eventually......or does he?
5b. Mega Lava Pirahna
This is harder now because he does more damage and he's on fire. Like before, extinguish the little Pirahna's with a jump. The Fire Pirahna will also be on fire. Jump on him and he'll extinguish....but now the little pirahna's can come back to life. After a while the Koopa with you will "charge" into battle but touches the lava and after breif dialogue, runs away. Keep your jump attacks up and use Parakarry and he will die.....this time for good.

6. Huff n' Puff
Oh my god this boss is probably the toughest, annoying, and hardest boss in the game. When you hit him, tiny clouds come out so you should use Lakilester's Spiny attack. It will get rid of the clouds. If you don't deal with the clouds Huff n' Puff will suck them up and get his health back. After a while he will get electrocuted and try to zap you. Avoid this attack at all costs!!! If it hits you it does 12 damage and you can't risk it. Use Bow to avoid this. Also, you can use Parakarry's Air Raid (Ultra Rank Attack) which does 8 damage to each enemy if the bar is at 100%. When he gets less HP you are in BIG TROUBLE. His attacks become more rapid and he gets health back much faster. Use Ultra Shrooms (or Whacka's Bump is the best thing to use) to heal your health.

7a. Crystal King's Minions
This isn't really a 2-part battle but you have to kill the crystals that he summons or else he can multi-attack you. There is a circle crystal, a square crystal, and a diamond crystal.
7b. Crystal King
This boss is relatively easy. Attack with your Jump attack and use Watt. He can heal his health, 10 HP, at a time. His attacks are damageable but you can avoid them. When you beat him only the Koopa King himself is left.....

8. Bowser in the Castle
This battle of Bowser is pretty easy. Although he has 50 HP he can only do 10-2 damage a hit. His fire breath is the only thing you should worry about. When he becomes invincible use Star Beam to make him lose invincibility....temporarily. Equip the Spike Shield badge so you don't get hurt if you jump on his head. Use Multi-Bounce, both Power Plus's, and the Ice Power Badge for an extra 1 damage. When you beat him he'll run to the top of the castle, where your final battle awaits you.....

9a. Bowser on the Castle
This is the toughest battle in the game. He has 99 HP, Fire Breath that does 12 damage and his Star Rod Invincibility power. Just hurt him and do damage until he becomes invincible. After a while the battle will get worse and switch to Peach and Kammy Koopa (see section 9b. below). When you get the Peach Beam, you can get rid of his Ultra-Invincibility and comtinue with the battle. Use lots of Whacka's Bumps to heal your HP and FP and kick Bowser's booty all the way to High-Heaven and rid of this Evil Koopa King once and for all.
9b. Kammy Koopa and Twink
This doesn't even take talent. Just attack her and use Peach's Focus to upgrade Twink's AP (Attack Power). When she dies you will get the Peach Beam to get rid of Bowser's Ultra-Invincibility.

Section II: Miscallenous Boss Fights:

1. Jr. Troopa
This is the only "Boss" you'll fight through the game after-before each chapter. Every fight he gets a new power-up each time. Here is a list of his power-ups:
Prologue: Reqular old Self
After Chapter 1: Spike Hemlet
After Chapter 3: Wings and Spike Helmet
After Chapter 5: Egg Protector Shell
After Chapter 7: ????????????
Inside Bowser's Castle: Wings, Spike Helmet, More Damage, and better protection.

2. Fuzzipede
This isn't really a boss but you fight him in "The Giant Tuna's" belly.

3. Lakilester
Just use Jump atatcks and Parakarry's Shell Shot to defeat this minion of Huff n' Puff to make him join you.

4. Kent C. Koopa
A very annoying boss to fight. With 70 HP, 3 reduced damage, and annoying attacks, he is very tough. Use a Multi-Bounce and Power Plus's to defeat this "Psycho Koopa".

5. Twin Goomba's
These 2 Goomba's are the second boss you fight. The blue one has 7 HP and the red one has 8 HP. just jump and use Goombario's headbutt, just in case.

6. Goomba King & Twin Goomba's
Now you have to deal with the king himself! At the start hit the Goomnut Tree's "X" to get rid of the Twin Goomba's and do 4 damage to the king. Just keep Jumpin' and he will admit defeat and show the way to Toad Town

Section III: Toad Town Tunnels Bloopers:

1. Mini-Blooper
At only 30 HP he's a pretty easy enemy to fight. There's not many tips on this since he's so easy. Just jump, dodge, and heal to beat him.

2. Electro-Blooper
He has 50 HP and can Electrocute himself for defense. Use Parakarry's Shell Shot to De-Electrocute him. Just jump on him and you'll beat him.

3. Super Blooper
The Final Blooper you fight. He has 70 HP and he is pretty powerful. Just jump on him and Shell Shot him to Victory!!!

Section IV: The Dojo

1. Chan
He only has 15 HP and is like a Koopa, flip him and deal the damage.

2. Ghost Fighter (I forgot his name)
He has 30 HP this time and can copy your partner's looks and abilities. He is easy if you practially master the game.

3. The Master "1"
The Master has 50 HP the first time. his multi-attack can do 4, 5, then 6 if you don't block the time. Hammer him and Shell Shot him until he dies.

4. The Master "2"
This time he has 70 HP. Jump attach him and equip the Shock-Attack badge so when he hits you, he'll get hurt also.

5. The Ultimate Master
Thefinal time he has 99 HP and a lot of power and defense. I don't have tips since everyone fights him differently.

Original Mario
Go to Boo's Haunted Mansion and enter it. Once you get in the door continue walking straight until you come to a wall. Walk to the right until you see a door. This is the door farthest to the right. Walk into where the door leads you. There should be a large pot and a crate to the left. Jump on the crate and jump into the pot from there. When you jump out, you will be the original NES version of Mario. Note: You cannot leave the room with this trick on.

Luigi's secret diary
Once you have the Super Boots and/or the Ultra Boots, go into Mario and Luigi's bedroom in Mario's house. You will see a square of boards facing the wrong direction. Do a special jump (press A while in the air) to go into the basement. Look at the book on the table to find Luigi's diary.

Answers to the Bowser questions
The answers are as follows: "3", "Red", "Red", "24".

Never-ending hallway pattern
The pattern to the "Never-ending hallway" is up, down, up, down, down, up.

Ultra-Level party members
Once you visit Raphael the Raven, you can "Ultra-Level" your party members. The best one to "Ultra-Level" is Parakarry, because he learns "Air Raid," which uses 6 (or 8) FP, and deals about 6 damage to each enemy (if you get to 100% on the "Press Left repeatedly" meter).

Easy Way to beat the Koopa Bros.
If u are a lot like the old me, you go for power over tactics, in which you would use Bombette's bomb attack. Instead, fight fire with fire, and use Kooper's shell attacks. When the Koopa's get into their shell tower attack use your hammer and Kooper's shell attacks to bring down the tower and spill them on there back disabling them for one turn. Then use Kooper's super spin dash to wipe out of them at once, and if you have the badge use Mario's multibounce. BASICALLY THE KEY IS ATTACKS THAT TARGET ALL ENIMIES, BUT THE BOMB BECAUSE THAT USES TO MUCH FP AND YOU WON'T HAVE ENOUGH ATTACK POWER!
