Invoice

The Invoice is a key item used as part of a request to restore Ilia's memory in Twilight Princess. This item can be obtained after showing Telma Renado's Letter. The Invoice goes in depth on the town doctor's tab, which seems to be an astronomical amount. There is a number on the Invoice; 176,480,000. This might be the amount the doctor owes. After taking the invoice to said doctor, whom is found in the Medical Clinic, he refuses to pay, but will allow Link to enter his office. There, Link is able to transform into Wolf Link and take the scent of some dropped medicine. He can then follow this scent to a certain location. The location leads to an item that is known as the Wooden Statue
