Bulrush Coming Through!
In this Super Mario Bros. Wonder Walkthrough, you'll find the complete guide to completing Stage Bulrush Coming Through! of World 1 with the locations of Flower Coin and Wonder Seeds.
Flower Coin 1/3
After starting the level, you'll find a tree to the right of several orange blocks. Make several rodeo attacks B + Y on the tree to bring it down. Head to the right and wait for the Bulrush to come at you. Jump to dodge it, and it will destroy the blocks that will allow you to collect the first Flower coin.
Flower Coin 2/3
Move forward to find a tree with a talking plant. Perform a rodeo attack to be sent flying. Go right to find the second Flower coin.
Flower Coin 3/3
The last Flower coin is stuck in several orange blocks to be destroyed. You'll need to lure the Bulrush to the tree on the left to make it reach the area and break the blocks. It's also possible to recover it by transforming into an elephant.
Wonder Seed 1/3
Completing this level automatically gives you the first Wonder Seed.
Wonder Seed 2/3
About halfway through the level, just past a slope, a Bulrush will charge at you. Head to the left and it will destroy the blocks in the air. You can then pick up the wonder flower, which will change the level.
Climb the Bulrushes and wait for them to destroy the level's end flag before reaching a cloud. You can then pick up the second Wonder Seed.
Wonder Seed 3/3
Simply complete the alternate end of the level after collecting the second Wonder Seed to obtain this third Wonder Seed.
