Now that you have defeated Bowyer and retrieved the second Star Piece, return to Rose Town and talk to Gaz in the Inn to receive Geno's Finger Shot weapon. Exit Rose Town to go to the World Map, then press Left on the Control Pad TWICE to reach Moleville.
Talk to the folks in Moleville to learn about Dyna and Mite, two kids who have been trapped inside the Mine. Now is a good time to stock up on any weapons, armor or items your party needs. Watch Bowser rally his troops in the top-right corner of town, then enter the Mine. When the moles in the Mine ask you to help them, say yes, then jump on their heads to reach the door above you. Explore the Mine until you find Pa Mole, then talk to him to learn that you need a bomb to blow up the walls.
Return to the room with the spring and jump on it to knock yourself silly. No joke! This is the only way to encounter Croco, who has the bomb you need. After you wake up and Croco runs off with your stuff, follow him (hold the Y Button to RUN) and jump on his head to enter a battle. Defeat Croco to receive the Bambino Bomb, then return to Pa Mole. Talk to Pa Mole to use the bomb and open a new path in the Mine.
Enter the newly-opened path, go up and right to the next screen, then go right and down to the next room. Take the top-right path to reach a room with a Save Box, then go up and right to find Punchinello and some Bombs. Jump on Punchinello to enter the battle. (If Punchinello pushes you out of the room, don't worry about it. Go back in and try approaching him from the side. He's nothing but a big bully.) Defeat Punchinello to get the third Star Piece!
After beating him, take the top-right path to the next room, then work your way down and left to reach a mine cart with Dyna and Mite. Ride the mine cart to exit the Mine and return to Moleville. On to the fourth Star Piece!
