Once you have retrieved the third Star Piece, exit Dyna and Mite's house to watch some Snifits chase a beetle. Exit Moleville to get to the World Map, then push Left on the Control Pad to access Booster Pass. Work your way up and right through the area until you return to the World Map, then press Left to access Booster's Tower.
When you first approach the tower, watch Bowser try to open the door. After Bowser leaves, walk up to the door and press the A Button to discover that the door is locked. As you begin to walk away, Bowser will return, open the door, and join your party. Enter the tower and climb to the top to find Booster's Toy Room. Take the door on the bottom-left side of the room to see Princess Toadstool on the balcony. After an automatic sequence, Booster and his Snifits will enter the room and try to find you behind the curtains. Whether you get caught or not, when the sequence ends, go through the bottom-left door to access the balcony. Defeat Knife Guy and Grate Guy, then go left to enter Booster Hill.
Once you've defeated Knife Guy and Grate Guy in Booster's Tower, go left to enter Booster Hill. Follow the instructions to race to the top of the hill and reach Marrymore.
Talk to the people in front of the Wedding Chapel in the top-left corner of the town, and Raz and Raini will automatically get thrown out of the Wedding Chapel. Face the Wedding Chapel's door and press the A Button to talk to Snifit 1 and learn about the back entrance. Walk down and right until you are standing on the green grass, then hold Up on the Control Pad until you are just past the edge of the first wall. Hold Left on the Control Pad to find the back door, hidden behind the wall.
Go down the stairs to find the bakery, where two cooks are working on the wedding cake. Take the stairs in the top-left corner, then walk up and left until Snifit 1 says, "Get lost." Press the B Button to continue, and he will ask you to help him break down the door. You and Snifit 1 must make contact with the door at the same time in order to break it down. After breaking down the door, you will enter a room with a Save Box. You and Bowser will need to break down the next door to get in to the congregation hall. You may want to save the game here while Bowser is trying to break down the door, since the next sequence can be difficult. To break down the door, you and Bowser will need to make contact with the door simultaneously. This will put you in the congregation hall, where Booster and Princess Toadstool's wedding is imminent.
Once you've entered the congregation hall in Marrymore, Princess Toadstool loses some of her possessions and the Snifits try to retrieve them all. You need to talk to each Snifit to get the item they found, then get the crown on top of Booster's head and talk to Booster. Chef Torte and his Apprentice will appear on the scene and attack your party. Instead of attacking Chef Torte and his Apprentice, attack Bundt (the wedding cake in between them), who is the real boss.
After you've rescued Princess Toadstool from the wedding, Raz and Raini will talk to you. Talk to everyone in town for clues, then return to Mushroom Kingdom. Enter the castle and go to the throne room to watch an automatic sequence, then exit the castle. As you walk outside, Princess Toadstool will float down. Talk to her and she will join your party. Next, talk to Frogfucius and go to Star Hill to recover the fourth Star Piece.
Once Princess Toadstool has joined your party, you're ready to get the fourth Star piece from Star Hill. Return to Tadpole Pond and talk to Frogfucius to find out that a large star has been sighted at Star Hill. Exit Tadpole Pond and go back to the World Map. Go left past Marrymore to reach Star Hill.
This entire area has small stars on the ground, star shaped flowers, and big stars with keyholes. The big stars lead to other screens and will only open after you've talked to all of the flowers in the area. Explore the entire area and look carefully in every direction -- it's easy to miss things here if you're not careful. Work your way through the area until you find the fourth Star Piece lying on the ground. Walk around the area to locate all of the flowers, then enter the big star to exit the area. Next, go to Seaside Town to get clues about the fifth Star Piece.
