[Zelda: Majora's Mask] Why does the moon have a face? Has it always had a face? And why is it an angry face?
gpt
There are some hints that the Moon in Termina has always had a face. The people know something is different with the moon (angry face) but never freak out nor question why all of a sudden it has a face. Most of them just seem to wonder why it is slowly getting bigger and has changed expression. The Mayor's chair also depicts the moon with a face on it, meaning that how the moon has always been depicted to them.

The Moon is angry due to Majora's influence. The Moon also cries and those tears are an item that Link can collect during his quest. So the Moon is self aware that it is closing in on Termina but sad that it cannot do anything to prevent it.
