Ocarina of Time
The Adult's Wallet is the first Wallet upgrade in Ocarina of Time. It allows Link to carry 200 Rupees, which is 101 more than he could hold previously. It is acquired by defeating 10 Gold Skulltulas, collecting the Gold Skulltula Tokens they drop, then going to the House of Skulltula.The first child who has been freed of the curse rewards Link with the Adult's Wallet in thanks. It can later be upgraded in the same way to the 500 rupee Giant's Wallet after collecting 30 tokens in total.
In Ocarina of Time (N64), the Adult's Wallet appears as a brown sack with a silver hexagon on the front, which looks very similar to a Silver Rupee. In Ocarina of Time 3D, the hexagon is blue instead.
The Adult Wallet is the first upgrade to Link's Wallet in Majora's Mask. As with the Adult's Wallet in Ocarina of Time, it holds 200 rupees. It is acquired from the Clock Town Bank; if Link deposits 200 Rupees into the Bank, the Banker rewards Link with the Adult Wallet.
The Adult Wallet appears in Majora's Mask as a pale brown sack with a silver hexagon on the front. This silver hexagon looks very similar to a Silver Rupee. It can be upgraded to the Giant Wallet by collecting 30 Gold Skulltula Tokens from the Oceanside Spider House (on the First Day only in the N64 version).
