World 1 - Bulrush Express All Wonder Seeds, Flower Coins, and Secret Exits - Super Mario Bros. Wonde
After hitting the second P-Switch in the course, the Bulrush stampede will jump off a ramp, and you'll careen toward two oncoming platforms sitting underneath a Warp Pipe. Instead of jumping off the stampede immediately, wait until they arch downward and hop off to land on the lower ledge. Quickly snag the Flower Coin, then jump onto the upper platform to safely return to the stampede.
Flower Coin 3 Location

To collect the final Flower Coin, ride the stampede past the third P-Switch, then leap over the trio of Snails on the hard blocks. Next, avoid the pair of Snails crawling upward and jump off the large Snail to propel yourself into the Flower Coin floating overhead.
Wonder Seed 1 Location

To obtain the first Wonder Seed, you must ride the stampede until you reach the red arrow that's pointing upward. Hop off the stampede, then leap upward to avoid the charging Bulrush, and you'll find the Wonder Seed beside a red Warp Pipe.
Wonder Seed 2 Location
