Jeffrey Parkin (he/him) has been writing video game guides for Polygon for almost seven years. He has learned to love just about every genre of game that exists.

Super Mario Bros. Wonder’s Petal Isles contains 34 Wonder Seeds and one Royal Seed. Our Super Mario Bros. Wonder guide will help you find all Wonder Seed locations in Petal Isles, including any hidden Wonder Seeds that unlock additional levels. If you’re looking for other worlds, consult our guide on where to find all Wonder Seeds.


Tips for finding Wonder Seeds

Nearly every level will reward you with one Wonder Seed just for reaching the flagpole at the end. But to find every Wonder Seed will take a bit more exploring.

Look for Wonder Flowers

Most levels will have a Wonder Flower to collect. This special flower triggers a trippy reframing of the current level — sometimes the gravity disappears or you enter a twilight realm or multihued bubbles will carry you into the sky. Many of the Wonder Flower sequences end with a Wonder Seed.

Some levels have extra Wonder Seeds

Some levels have a third, hidden Wonder Seed beyond the ones listed on the map. Collecting these Wonder Seeds often unlocks a new path to previously hidden levels — and more Wonder Seeds. We’ll note levels that require finding a hidden Wonder Seed in the list below.

Buy the Sensor Badge

When you reach W5 Fungi Mines, you’ll be able to buy a special Badge from the Poplin Shop there — the Sensor Badge. This Badge will ping when you are close to special pickups like 10 Flower Coins, Wonder Flowers, and, most importantly, Wonder Seeds.
