Third Course (Coin Challenge Pack A)
From the Super Mario Wiki
The level begins with Mario Ground Pounding a Sledge Bro to receive a coin shower. After getting past a few Sledge Bros and several Lava Bubbles, Mario will touch the Checkpoint Flag afterwards. He will then encounter several more Sledge Bros and Lava Bubbles, followed by a P Switch with an assortment of Blue Coins revealing the locations of Hidden Blocks containing Golden Mushrooms. Mario must then climb additional Donut Blocks to the Goal Pole.
