Listed in order of appearance in the game. Optional bosses are listed at the bottom of the page.
Hammer Bro
HP: 50
Attack: 6
Defense: 13
Magic Attack: 6
Magic Defense: 8
Resistances: None
Weaknesses: Jump
Items Dropped: Hammer and Flower Jar
Difficulty: Easy
Notable Attacks
Hammer Time: Hammer Bro will throw four hammers on this attack. Wait until about one second after all four hammers hit to do a defense timed hit. If left undefended, this attack can do 10+ damage.
Valor Up: Valor Up raises Hammer Bro's defense by 25, making him difficult to defeat. When you defeat one of the two Hammer Bros, the other one will immediately use this move.
Description
This fight can be difficult if you haven't gotten the hang of timed hits yet. If you aren't too sure of your ability for timed hits, Mario should be level 3 for this fight. If you are good with timed hits you should be fine with Mario at level 2. The best strategy for the Hammer Bros is to one Jump and one normal attack on each of them. Alternate these attacks, because Hammer Bro's defense is raised a ton when he uses Valor Up.
Croco
HP: 320
Attack: 25
Defense: 25
Magic Attack: 30
Magic Defense: 18
Resistances: Sleep
Weaknesses: Fire
Items Dropped: Flower Tab and Wallet
Difficulty: Hard
Notable Attacks
Bomb: This is a strong attack and can't be blocked. Usually does around 15-25 damage.
Weird Mushroom: Croco recovers 60 HP. He uses this when he's low on HP, but sacrafices two turns.
Description
Croco can be a problem if you aren't leveled enough. Mallow should be at least level 4 for this fight, otherwise Croco's Bomb attack could kill Mallow in one hit. When the battle starts have Mario use Fire Orb, this will deal upwards of 60 damage and make Croco lose his turn. Mallow won't be doing a lot of damage this fight, but his job is to heal with his move HP Rain. When Croco is at about 30% HP he will use a Weird Mushroom to recover 60 HP, but you get two free attacks when he does this, take advantage of it with another Fire Orb attack.
Mack
HP: 480
Attack: 22
Defense: 25
Magic Attack: 15
Magic Defense: 18
Resistances: Fear, Poison, Sleep, Silence
Weaknesses: Thunder
Items Dropped: 1st Star
Difficulty: Normal
Notable Attacks
Flame Wall: This attack hits all of your characters, but the attack doesn't do too much damage to be considered a hugh threat.
Flame: Flame is like Flame Wall except it only hits one person, but it does a lot more damage. Ideally you want this attack to hit Mallow because his Magic Defense is high.
Description
Mack will summon four Shysters at the beginning of the fight. If Mallow's Magic Attack is high enough at this point (Level 6 will guarantee this) then a single Thunderbolt will kill all the Shysters as well as deal a fair amount of damage to Mack. After destroying the Shysters, Mack will start using Flame and Flame Wall. Keep an eye on your HP, use Mushrooms or HP Rain when necessary. When Mack is low on HP he will re-summon the Shysters. If you have enough power to kill them all with one Thunderbolt, Mack will continue to summon Shysters over and over again this way until he dies. If you can't kill all the Shysters in one hit, then Mack will temporarily run away until all of the Shysters are defeated.
Belome
HP: 500
Attack: 30
Defense: 25
Magic Attack: 15
Magic Defense: 20
Resistances: Sleep
Weaknesses: Thunder
Items Dropped: None
Difficulty: Normal
Notable Attacks
S'Crow Funk: Turns one character into a Scarecrow. The Trueform Pin found in the Kero Sewers will protect against this.
Eat Mallow: Every now and then Belome will eat Mallow, leaving Mario by himself. Mallow takes no damage, but if Mario falls while Mallow is swallowed it's game over.
Description
Belome can be really easy if you have Mario's Super Jump at this point. If you don't have Super Jump, Thunderbolt and Fire Orb will suffice. Special attacks deal more damage to Belome than normal attacks. If you found the Trueform Pin, have Mario wear it. You don't want to be turned into a Scarecrow when Mallow is eaten because you won't be able to use items to recover. Keep some Mushrooms handy when Mallow is swallowed just in case Mario's HP gets low.
