Astral Observatory

The Astral Observatory is a small building outside the walls of Clock Town in Majora's Mask.

Location
Although the observatory is located in Termina Field, the only way for most people to get here is through a hidden passage in East Clock Town. It is home to a giant telescope, which is able to view the entire landscape of Termina, and it also serves as the hideout of the Bombers Gang.

The passage to the observatory is guarded by one of the 6 children of the Bombers, who must be told a 5-digit password in order for Link to gain entry. The password is acquired by popping the balloon in North Clock Town, talking to Jim, finding every member of the Bombers hidden throughout town, and proceeding to tell the password to the Bomber guarding the passageway. Once Link regains his Hylian form and returns to the first day, he can play the game again to reenter the underground tunnels.

Once Link enters the tunnels, he must go through a small sewer, defeat a Skulltula, destroy another balloon, then go up the ladder leading to the observatory itself.

Link can also use a Deku Flower in Termina Field to enter the Observatory, although curiously it is not present during the Retrieval of the Ocarina of Time.

Features
At the entrance, Link can meet the famous dancing scarecrow. Upstairs, the young hero will find the astronomer named Professor Shikashi with the huge telescope overlooking Termina Field. There is a Moon's Tear encased in a glass next to the telescope, and upon checking it, Professor Shikashi comments on how he finds the stones falling from the Moon's eyes, and how they have been falling recently. By using the telescope to gaze at the Moon, Link can obtain his own Moon's Tear, which is required to start the Deku Flower Trading Quest.
