Here are 2 unnamed pony life background ponies, the orange and green earth mare and the powder blue earth mare. There cutie marks are a rainbow and a cloud for the orange and green mare and a rain cloud for the powder blue mare. I think for the powder blue mare because I really like her design, I was thinking Misty Rain or Sky Blue.

Might as well throw in the other wiki placeholder names for the Sailor Moon ponies in here. They seem to be based on moons/satellites of each planet, apart from the Roman festival Saturnalia.
