Claim Check

In Ocarina of Time, the Claim Check is used to obtain the Biggoron Sword. It is recieved from the Biggoron after Link finishes the trading sequence. After he gives it to Link, he must wait three days and return. Link can make three days go by either waiting it out, and or by playing the Sun's Song. If the young hero shows Biggoron the Claim Check after three days, he will give Link the Biggoron Sword.
