Light-Switch Mansion – Super Mario Bros. Wonder Guide

Here’s every Wonder Seed and Flower Coin in Light-Switch Mansion, the third level of Fungi Mines in our Super Mario Bros. Wonder walkthrough.

So, what are we looking for? This level has two Wonder Seeds and three Wonder Flowers to collect. No secret exit this time. You’ll also want to hop onto the top of the flagpole if you’re going for 100% completion.

We’ll list all the collectibles in the order that they appear. Some of the really basic ones don’t have an image because the text is pretty self-explanatory. Feel free hop around to your needed collectible:

Flower Coin 1

As the lights show, there are invisible blocks underneath and to the left of the Flower Coin. Jump up there from the invisible blocks on the left.

Flower Coin 2

See all the coins and blocks in the background? Get there by stunning the mimic door and entering its door. Once there, use the light blocks to illuminate the hidden platforms. If you want to skip all that, enter the door and immediately jump to the platform on the right. From there, jump to the left and you should be able to reach the Flower Coin with ease.

Flower Coin 3

Don’t overthink this one! There is a single platform of invisible blocks circling underneath this Flower Coin. Ride it until you are in grasp of the Flower Coin!

Wonder Seed 1

This one is required to collect! King Boo will appear and sing his heart out as you make your way through the next minute of this level’s antics. Survive and collect your Wonder Seed at the end.

Wonder Seed 2

Reach the end of the level.

Golden Flag

Climb up the stairs made up of invisible blocks and use them to reach the top!
