Cloudy Tile

Cloudy Tiles are a type of Weather Tile, which spread Shade. Generally, the effect of Shade is that it causes Flowers to Wilt, unlike Sunlight spread by Sunny Tiles which generally help Flowers to Bloom.

In Sunny Side Up: Cubed
In the Cubed version of the game, Clouds have a range of 1 space.

Technically, the Cube doesn't have Tile at all. Internally, they're still referred to as Cloudy Tiles however.
