Nimbus (Japanese: 雲の国 Kumo no Kuni;Cloud Land)is a location in Miitopia. It's located high above the ground, right above the Travelers' Hub. Nimbus is made up of several clouds, on which people can walk on. It is found shortly after unlocking the aforementioned Travelers' Hub and is the location of one of the Sky Scraper Jewels, the Sterile Plant.
Featuring several robotic enemies, such as the Robo-Pengy and the Mecha Goblin, Nimbus is clearly a very futuristic area, possibly militaristic in nature due to the amount of weaponized enemies.
The name derives from the word nimbus. Nimbus describes either a large grey rain cloud, or a halo surrounding a saint or supernatural being. The latter seems to be ironic, considering how close it is to the Sky Scraper housing the Darker Lord.
