Pouch

The Adventure Pouch is an item that sits at Link's waist that appears in SS undefined. Fledge gives this item to Link to aid him in his quest to find Zelda. The pouch can hold up to four items when Link obtains it, but various upgrades increase its capacity. Each upgrade allows Link to carry an extra item in the Pouch. The Adventure Pouch can be upgraded three times at Beedle's Shop for 300, 600, and 1200 Rupees respectively, and a final upgrade rests in a Goddess Cube Chest at Pumpkin Landing that can be unlocked using a Goddess Cube found outside Skyview Temple.

The adventure pouch can hold Medals, Shields, Bottles, Quivers, Bomb Bags, and Seed Satchels. When one of these items is obtained while the Adventure Pouch is full, the obtained item will be send to the Item Check in the Skyloft Bazaar. The main way to obtain items for the pouch is by searching for Goddess Chests.

If Link has the Cursed Medal equipped, he cannot open his Adventure Pouch and cannot equip a shield, but it does increase the odds of finding treasure and Rupees more often.

Trivia

 * Beedle denies that the price increases every time Link tries to buy a new, more expensive Adventure Pouch.
