You can't........humanly.
Tingle in legend of Zelda Majora's mask floats in his balloon. After you pop it by Deku links bubble or by arrow he falls to the ground and then you can buy maps for different locations where he is differs what maps you can buy. In legend of Zelda wind waker he stays at Tingle island south of Windfall island, he is used to decipher Triforce charts for a hefty price. Most of the time over 200 rupees. Did that help?
Tingle charges 398 ruppees to translate a triforce chart so save up about 3190 for him to read all of them
tingle should mail the locations to you but you need a rupee pouch that carries more than 200 ruppees. you can get one from the great fairy.
If you mean the last triforce shard, you have to find it on the sea maps after getting them translated by Tingle. If you mean how you get the last part of the Triforce (the Triforce of Power), you can't. Ganondorf has it, and you're not supposed to get it.
You have to bring the charts to Tingle Island to get them deciphered.
If you are talking about Wind Waker, then you go to tingle on tingle island, and pay something around 584 rupees...for just one map.
It shows you where all of the triforce charts are. Once you find them, tingle has to identify them for 398 rupees each. After he identifys them, it will also show the location of the triforce shards.
Find all eight triforce pieces and return to Hyrule (find Tingle on Windfall).
If you get the In-credible chart from Tingle, it'll show you all the locations of the charts. When you've found one at it's designated spot, pay Tingle at the Tingle tower 398 ruppes/chart (You will need the giant Ruppee bag) and he will mark the location on your In-credible chart.
go to tingle island and talk to tingle at the top of his tower he will ask to dicipher the sea chart for 398 rupees which means you will have to get a bigger wallet to dicipher it. the fairy on outsetwi wallet and so will another fairy by windfall
Tingle. (shudder) He will do it for a crazy amount of rupees (3184 rupees in total, 2500 if you got all 5 Dragon Tingle statues), so make sure you have a lot of rupees and the largest wallet.
Tingle (the guy locked in prison on windfall island) who lives on Tingle island. You can warp there using the Ballad of Gales song and have him translate them for you. WARNING: Translating the charts is REALLY EXPENSIVE. (It costs about 400 Rupees)
