@the people asking what cosmog/nebby is
"Cosmog is a small Pokémon with a gaseous body similar to a nebula. It has two wisp-like extensions that serve as arms and an ellipse running down its body. Its front and back are black in color. It has yellow eyes and two blue cheeks. In behavior, Cosmog has an overly trusting nature and it immediately takes a liking to whoever shows it kindness, even when that person doesn't have the best intentions for it.
Cosmog has the ability to open Ultra Wormholes, but only when under stress, and this process is very dangerous for Cosmog. Cosmog can be created by Solgaleo and Lunala at the Lake of the Moone/Lake of the Sunne."
