The Legend of Zelda: The Wind Waker/Triforce of Courage

Tingle
In order to decipher the many Triforce Charts you will find in the game, you will need Tingle (his island is at C3). You will need exactly 3,184 rupees (398 per map) to decipher all eight Triforce Charts and reveal the location of all eight Triforce Shards. If you saved up before that, that's how much you need to reveal the shards or the Triforce of Courage which is under the sea!
