In South Clock Town go to the west side where a Deku Flower is located. A Business Scrub will float in when you get close, this is his private property.
He is willing to trade this property, including the Deku Flower, for a Moon’s Tear to give to his wife. This is good news, you have a Moon’s Tear! Equip it and show it to the Business Scrub to acquire the Land Title Deed .
Piece of Heart #1 - Use the Deku Flower to fly to the entrance of the Clock Tower and acquire this Piece of Heart.
You can’t enter the Clock Tower until midnight of the third day, so now is a good time to collect rupees and store them in the bank in South Clock Town.
