Rolla Koopa Derby
In this Super Mario Bros. Wonder Walkthrough, you'll find the complete guide to completing Stage Rolla Koopa Derby of World 1 with the locations of Flower Coin and Wonder Seeds.
The Koopas and skates course is located in the area north of the second zone.
Flower Coin 1/3
Move forward to find the first Flower Coin between the Koppas. Eliminate them to retrieve the flower.
Flower Coin 2/3
After obtaining the first Flower Coin, move forward to find two yellow blocks high up. Jump under the right-hand block to reveal a chopper flower which takes you to a secret area. Jump several times under the springboard to launch the shells high up to get rid of the Koopa. You'll then need to do this one last time to get the Flower Coin.
Flower Coin 3/3
Continue through the level to find a yellow block in the wall. You'll need to use a Koopa shell to throw it into the yellow block. You can also use the elephant's trunk to retrieve the Flower Coin from the block.
Wonder Seed 1/2
Move on to find a switch on a large tree. Activate it to reveal a wonder flower. Your aim is to find all five flowers in your path. When you've got them all, the Wonder Seed will appear at the top.
Wonder Seed 2/2
You'll get this seed automatically by completing this Mario Bros. Wonder level.
