I want to learn how to make a moon pool me and my friends have a mermaid coven, so we want to make one

I originally THINK:

1. anda don't make one, anda find one.

2. The moon is always far away so make sure its INSIDE a high bukit, hill where there is SEA WATER not SWAMP WATER.

3. And the has to be a hole in the puncak, atas for anda to see the moon.

4. Make sure the water is deep and has entrance somewhere inside.

5. If anda really want to MAKE ONE dig a whole in bukit, hill where the moon is facing i think mostly its EAST.

6. This step is no help its a question..... can i gabung you'r coven?
Im ten.....AND you'r probably older so go ahead say NO also I THOUGHT that was the answer.
