This world is exactly what it sounds like: it is merely just a blue sky with clouds. At night, the clouds collect under the floor and the moon is visible in the night sky. The colorings of the floors are different in each variation - Day is orange and amber with blue railings while Night is blue-green and gray.
Not much else is known about this world as it is exclusive to the sole game it appears in, though it may have had inspiration for Mid-Sky.
