Hidden Treasures & Secrets: Marrymore

From the Marrymore entrance, go up the stairs to the northeast, then turn northwest and ascend another flight of stairs to find the inn/shop.

Go upstairs inside the inn and through the double doors to the northeast to reach a room.

Jump on a bookshelf to the west and jump again from this elevated position to find a Hidden Chest containing a Frog Coin.

Head downstairs and talk to the shopkeeper (the larger, leftmost person behind the counter).

The shop sells the following items: Mid Mushroom (20 coins), Maple Syrup (30 coins), Super Hammer (70 coins), Whomp Glove (72 coins), Hand Gun (75 coins), Fake Chomp (60 coins), Happy Shirt (38 coins), Happy Pants (38 coins), Happy Cape (38 coins), Happy Shell (38 coins), and Nurture Ring (145 coins).

Exit the inn/shop, go down the stairs to the southeast, then turn northeast and head up the stairs towards the wedding hall.

To enter the wedding hall, head southeast from the front doors, then turn northeast around the side of the building. Search behind the southernmost tower for a hidden door.

Once inside, head southwest down some stairs to reach the kitchen.

Go up stairs to the northwest. In the next room, a Snifster will call you out. Jump when prompted to start the Door Crashing Minigame with a Snifster. You must run and make contact with the door at the same time as the Snifster.

In the next room, use the nearby save point. Investigate the locked door to start the Door Crashing Minigame with Bowser. Bowser shouts twice before charging, making timing easier.

After smashing through the door, talk to the three Snifsters to recover Peach’s accessories.

Jump up on Booster’s head to retrieve Peach’s crown.

Talk to Princess Peach.
