Whenever the Moon came out at night, she would be scared of the ocean, because of what the ocean did to her. The Moon would try to run away from it and would hide little by little as she ran away.
After the Moon fully hides, she would miss Granny Margo and would slowly show herself again and would eventually come back.
When she comes back again, she would stay awhile to see Granny Margo, but would, later on, remember about the ocean and with fear, she would try to run away.
This cycle would keep going on and on. This is the reason why the Moon has phases and the Moon shows different shapes everyday and repeats the shapes in a fixed pattern with a specific amount of times.
However, there would be a time where the Moon would change her appearance into a not so friendly look.
If the ocean jumps up while she is at the sky meeting Granny Margo, the Moon would get very irritated and because of her anger, she would turn into a reddish color.
