North Clock Town

In The Legend of Zelda: Majora's Mask, Clock Town area leading to Snowhead Mountain. In this area Link can find the first Great Fairy Fountain where after helping the Great Fairy he recives the ablity to shoot magic bubbles as a Deku Scrub and the Great Fairy Mask. In this area is also Tingle which will sell you maps. Also you'll find the leader of the Bomber Gang trying to pop a baloon, if you pop it as a Deku he will challenge you to a hide and seek game through Clock Town and after beating them you will recive their secret code to enter the Astral Observatory. Also the thief Sakon will rob the Lady from the Bomb Shop at midnight in the First Day, to stop him from stealing the Bomb supply slash him with your sword and he'll drop the supply. An alternate form is to shoot an arrow at him but instead of stopping him the bombs will explode and Sakon will die (and I really mean it he does die until you go back in time). You can also find a piece of heart atop of the tree and you can found a Keaton with the Keaton Mask by slashing all the running bushes in the area with the slide.
