This section covers strategies for defeating the various types of Wandering Hammer Brothers and the Koopa Kid boss battles in Super Mario Bros. 3. The Koopa Kid Room maps are courtesy of Derek "Pegboy" Kader.

Hammer Brothers

These are the Wandering Hammer Brothers found in Worlds 1, 3, 5, and 6. They may appear in levels with one or two levels of bricks.

• Strategy: Hitting the bricks underneath them is a reliable method.
• Fireballs: Effective for hitting them from afar when they jump to ground level.
• Hammers: Work well against Hammer Brothers positioned one level above Mario.
• Tail Attacks: Raccoon Mario or Tanooki Mario's tail swipes can defeat them if they are directly in front.
• Starman: Using an Invincible Starman before the battle makes them easy to defeat.

Boomerang Brothers

These Wandering Hammer Brothers appear in World 2, positioned on an elevated block.

• Strategy: Fireballs are great for hitting them before hiding at Mario's ground level. Wait for their Boomerangs to start their pattern, then hop off their head and avoid the returning projectiles.
• Starman: Using an Invincible Starman before the battle makes them easy to defeat.

Fiery Brothers

These are hidden Wandering Hammer Brothers in World 2. One is on the ground, and the other is on an elevated block.

• Strategy: Use fireballs to defeat the first one before it attacks. Then, jump up and use a fireball on the second one from Mario's safe ground position. Alternatively, you can jump on the first Fiery Brother's head and use momentum to reach the second while avoiding their fireballs.
• Starman: Using an Invincible Starman before the battle makes them easy to defeat.

Sledge Brothers

These Wandering Hammer Brothers are found in World 4, with one Sledge Brother positioned at ground level with Mario.

• Strategy: Fireballs are effective for hitting the Sledge Brother. Jumping on its head is more difficult due to their hammer attacks and ground shakes, but possible.
• Starman: Using an Invincible Starman before the battle makes them easy to defeat. Be sure to avoid standing on the ground when the Sledge Brother lands to prevent it from wasting your Starman.

Koopa Kid Battles

Larry Koopa

Larry is a simple boss with no special powers other than his Magical Wand. His room features a basic layout.

• Defeat: Stomp him three times or hit him with ten fireballs.

Morton Koopa Jr.

Morton is a simple boss with no special powers other than his Magical Wand. His room has more uneven terrain than Larry's.

• Defeat: Stomp him three times or hit him with ten fireballs. This battle is slightly more difficult due to the uneven terrain.

Wendy O'Koopa

Wendy is a tougher boss who sends red and white rings around the room and jumps frequently. Her room is flat, allowing her to move and jump more actively after each stomp.

• Strategy: If using fireballs, you will only contend with her initial red and white ring attack.

Iggy Koopa

Iggy is a simple boss with no special powers other than his Magical Wand. His room has uneven terrain.

• Strategy: Be careful due to the uneven terrain. He tends to shoot smoke rings slightly faster than Larry or Morton Koopa Jr., often throwing two sets in a row.
