First of all, any moon with a face on it is bound to look creepy, but the monstrous face on the Majora's Mask moon looks like it was custom made to enter your nightmares.
Anyway, for the uninitiated, the moon in this game started off as a harmless lunar body orbiting at a safe distance above Termina (the alternate reality version of Hyrule field). Things were changed when a skull kid (yes that's what he's called) wielding the powerful and mysterious Majora's Mask makes the decision to bring down the moon and destroy Termina.
|You can all thank this guy for trying to pass off mass destruction as a prank.|
The slowly falling moon takes center stage in Majora's Mask, where Link has three days to reverse the wickedness of the skull kid before the moon smashes into Termina. A nice touch is that the moon is actually falling in real-time, and as the hours go by you'll notice it getting ever larger as it descends upon Clock Town (the central town in the game). If you happen to use up all three days without saving the world, you'll be presented with a cutscene of the moon causing Armageddon.
|The future isn't looking too bright.|
|Apparently the moon even has its own sun orbiting around inside it.|
