In the first three-day cycle of Majora’s Mask there’s really not that much you can do. I’m stuck as a Deku Scrub, so therefore I’m stuck inside Clock Town. I found the one Stray Fairy that was missing from the fairy in Clock Town. It was located down by the water in southeast of Town. She gave me magic powers.
I also collected some rupees, bought a map for Clock Town and completed the search for the ”Bomber boys” so I could join the ”Bomber’s Secret Society”.
Finally I went to the Observatory, found a Moon tear that I traded with the Deku Scrub infront of the Clocktower in order to get his Deku Flower. Then, once I where in possession of the flower I just waited for the final night when the door in the Clocktower would open.
When the door opened I used the flower to fly up to it. There I collected a piece of heart and entered the roof where I faced Skull Kid. I took back the Ocarina of Time from him, player Song of Time and returned to the dawn of the first day.
