The Raincloud is a creation in Drawn to life.
How Creation Works Edit
After the sun page is found, The Mayor sends The Hero to find The Raincloud Page to equal out the weather. When it is found, they are given a square outline which they must draw in. Once drawn, it can be seen from the Observatory, as well as the Sun, and Night Sky. They also get to choose the color.
This is not the only Cloud Page in the game,
