Cloud Kingdom

The Cloud Kingdom is a kingdom in Super Mario Odyssey, and the greater location of Nimbus Arena. A mysterious realm in the sky made up entirely of clouds, the arena within this kingdom is the location of the first Bowser fight in the game, as well as the smallest location within the game.

Description
Nimbus Arena is mainly comprised of one main cloud platform, surrounded by a few smaller platformers, connected by Cloud Hats. Most of the smaller platforms, outside of the one the Odyssey lands on, do not appear until the Moon Rock found within the arena is broken.

The in-game brochure suggests that the Cloud Kingdom was once home to a society that had some connection with the moon, pointing out the moon phase markings and strange cloud arches found upon and around Nimbus Arena.

Power Moon locations
There are a total of 9 Power Moons in Nimbus Arena, the second lowest number after Culmina Crater, which only has one.

Life Above the Clouds
''Perhaps everyone has had the experience of looking up in the clouds and imagining what it would be like to live among them. As it turns out, as fantastical as it may sound, there was once such a kingdom whose citizens looked down on the world from a fluffy, puffy paradise.''

Strangely Floaty Material
''While the particles that make up a cloud are extremely small and light, researchers have recently discovered a kind of cloud-like material that one can walk on. First discovered in Fossil Falls, this substance can change into and hold new shapes and even support weight.''

The discovery prompted certain researchers to open an investigation into whether there might have once been a "cloud kingdom" in the sky.

Vestiges of Greatness
Once researchers started looking for places in the sky, they quickly found a large platform of the levitating substance, dubbed Nimbus Arena.

''Mysteriously, the land had markings that accurately showed the waxing and waning phases of the moon. Now, besides the obvious "how," researchers had to question "why?"

Giant Cloud Arches
''Researchers are thus baffled by the large cloud archway here. Some theorize that it's a kind of reticle that aligns with the moon. Some evidence suggests that the arch pulled this kingdom's Moon Rock to a specific location from the moon.''

The only certainty is the the Cloud Kingdom will continue to interest researchers for many years.

Shower of Flowers
''The investigation is concluded now and yielded few undisputed facts. But the bits of cloud that fall like flower petals here make it the most dreamlike place you'll ever visit.''

Symbols of Peace
''Perhaps signifying how peaceful this place is, many doves can be found living here. Supposedly, spotting a flock of doves will grant you increased happiness.''

Three Keys to the Kingdom

 * 1) Navigate the vast sea of clouds that seem to go on forever.
 * 2) Feel the unyielding cloud-floor that won't budge no matter how you stomp.
 * 3) Explore the remnants of the civilization that once existed here.
