Mario Bros. Wonder Special World – How to unlock all levels

Super Mario Bros. Wonder Special World levels are the hardest in the game, but it will require some puzzle-solving to find all their entrances and unlock them.

Just like in previous Mario games, there is a tough Special World hidden in the game, in addition to its normal worlds. There are six standard Special World levels, and at least three more to unlock.

An entrance to each Special World level is hidden on the six standard worlds in Super Mario Bros. Wonder, as well as Petal Isles. In order to unlock them, you’ll often need to find secret exits.

Read on to find out how to unlock all Special World levels in Super Mario Bros. Wonder.

How to unlock Special World levels

In order to reach the Special World you’ll need to find special propeller flower entrances hidden on the world maps.

Often, these Special World entrances will only appear after you’ve activated a secret exit or located a hidden path.

There are seven Special World entrances in total, one hidden on each of the world maps, as well as Petal Isle.

Each entrance will give you access to one super-tough level on the Special World map.

World One Special World Entrance: Pipe-Rock Plateau

In order to unlock the World 1 Special World entrance, you’ll need to reach the secret exit in the level Bulrush Express.

Activate the Wonder Flower effect and ride the stampede as usual until you reach the Wonder Seed at the end of the stage. At this point, you’ll need to be in Elephant form.

Smash the blocks to the right of the Seed, and you’ll reach the secret exit.

You’ll then need to complete three levels before reaching the Special World stage Bounce, Bounce, Bounce.

World Two Special World Entrance: Fluff-Puff Peaks

In order to unlock the World 2 Special World entrance in Fluff-Puff Peaks, you’ll need to complete the levels Jump! Jump! Jump! and Expert Badge Challenge: Spring Feet.

Complete the Expert Badge Challenge for Spring Feet, and you’ll next reach the entrance to the Special World, where the stage Climb to the Beat will be waiting.

World Three Special World Entrance: Shining Falls

Unlocking the World 3 Special World entrance in Shining Falls is easy.

To unlock the propeller flower, simply return to the Royal Seed Mansion a second time to speak to Master Poplin. He’ll make a new route appear to the Special World, where the stage Triple Threat Deluge will be waiting for you.

World Four Special World Entrance: Sunbaked Desert

The World 4 Special World entrance requires a secret exit on the level Secrets of Shova Mansion.

To unlock it, play the stage as normal until you reach the room before the standard flagpole exit. Here you’ll see six smashable blocks in front of a green moveable platform. Destroy the blocks, push the platform inside of the nearly created gap, and a gold pipe will spawn and lead you to the secret exit.

This will spawn two more levels on World 4. Beat them, and your reward is the entrance to the Special World level Pole Block Allure.

World Five Special World Entrance: Fungi Mines

Unlocking the World 5 Special World entrance in Fungi Hills is another easy one.

Simply return to Operation Poplin Rescue for a second time, and the Poplins will spawn a Special World entrance right next to the world exit.

Use the entrance and you’ll be able to take on the level Dangerous Donut Ride.

World Six Special World Entrance: Deep Magma Bog

In order to to unlock the World 6 Special World entrance you’ll need to progress deep into the world bu collecting many Wonder Seeds.

Eventually, you’ll be able to make your way to the very bottom left of the world map and, by completing a series of expert badge challenge levels, you’ll reach the Special World entrance.

This will take you to the Special World level Solar Roller.

Petal Isles Special World entrance

The Petal Isles Special World entrance will appear in front of the entrance to World 1 as you progress through Petal Isles.

In order to spawn it, unlock and complete the stage Wiggler Race – Spelunking! to complete the loop around the world.

Your reward will be a warp to the Special World level Way of the Goomba.
