-----------------------------------World Three------------------------------

Understand the map key: S (Start), X (Level), P (Pipe), F (Fortress), R (Rock), H (Spade House), T (Toad House), W (Wandering Hammer Brothers), L (Locked Door), C (Castle), B (Bridge), N (Canoe).

Locate Toad Houses (T) for items: House #1 has a pre-determined Frog Suit. Houses #2, #3, #4, and #5 offer random items including Fire Flowers, Raccoon Leaves, Frog Suits, and Super Mushrooms.

Encounter Wandering Hammer Brothers (W) who may fight on land or with water interference for Regular Mario. Brother Set #1 uses Hammers, and Brother Set #2 uses Invincible Starman.

Level 3-1: Start by hugging the left to find a power-up before proceeding right. Past air pipes and a Blooper, choose a path. Option One: Swim to the top of a wooden block wall, go over it, and find a power-up in a cubby hole. Option Two: Head down the right corridor, swim past a pipe, Lava Lotus, and another pipe, collect coins, and get a power-up from a ? Block. Rejoin by heading right along the water, passing Bloopers, to a pipe by a wooden block wall leading to the exit. For extra coins and a 1-Up, go down through floor holes, fend off a Lava Lotus, navigate Note Blocks, and head up to the exit pipe. Hit the Slot Box to finish.

Level 3-2: Jump across lifts, fall to a Donut Block, and collect a power-up. Position on the left of the next lift, run and jump to a Wooden Block platform above to dislodge an Invincible Starman, then grab it. Hit the second ? Block (preferably on the left) for another Invincible Starman, followed by a third ? Block with an Invincible Starman on a two Donut Block ledge. Take the next lift right, dodging Cheep-Cheeps. Hit the third block from the left to reveal a P-Switch. Activating the P-Switch creates a ledge near a pipe with a Venus Fire Trap for easier access, though jumping directly to the pipe is possible. After coming through the pipe, avoid a Cheep-Cheep and hit the Slot Box. Raccoon Mario can fly up to find seven Coins and a 1-Up.

Level 3-3: This level features rising and lowering water. Avoid Boss Bass, which can swallow even Super Mario, and Cheep-Cheeps. Go right to a Note Block containing a power-up. If it's a Super Mushroom, stomp a Green Koopa Troopa, kick its shell to break bricks, and get the mushroom. Aiming the shell left in the depression to the right of the power-up reveals a P-Switch for collecting coins from changed bricks. Jump across two gaps, then to a tall, skinny platform. Wait for the rotor platform to stabilize to use it as a stepping stone.
