At one time, it was known only by the kings of Alola and their heirs, and it was called “the child of the stars.” The Aether Foundation is researching this unusual Pokémon, and one of the professors at the foundation recently dubbed it Cosmog."
"Its gaseous body is so lightweight that it’s sent flying when the wind blows. When light falls on this Pokémon, Cosmog absorbs it and grows."
Also if you look closely inside the shell of the middle evo it looks similar to a Cosmog with it's eyes closed.
