Figurine Shop
From Zelda Wiki.org
The Figurine Shop appears in The Minish Cap and is run by Carlov the sculptor. It's entrance is a clump of bushes found in the south-west corner of Hyrule Town.
The figurine shop actually functions as a drawing, where Link trades Mysterious Shells for a chance to win a figurine. Figurines are of the various people, creatures, and enemies you meet throughout the game. The starting price for a drawing is 1 shell. As more figurines are won, the chance of winning a new figurine for your collection decreases. The probability can be raised by betting additional shells, and by exploring new areas. Carlov will make newer figurines as you meet newer friends and enemies.
The figurines won are kept by Carlov in a display case in the Figurine Shop for Link to view. Carlov will buy back figurines drawn that are already in your collection for 5 rupees.
There are a total of 130 figurines to be won, with six more added to collect upon completing the game, making the total 136.
The reward for collecting all of the figurines is given by the man sitting outside Mama's Cafe. He will let you inside his house, which contains a Piece of Heart, three chests with 200 rupees each, and a phonograph accessing the Sound Test.
Trivia
The Figurine Shop bears several similarities to the Nintendo Gallery from The Wind Waker, both providing the same function and both being run by Carlov.
