Eloise and Poodleoo Tittletat own the largest used rocket lot on the planet Pillbox.
They are unrelated, born in different years, and look completely different, but decide that they are twins as son as they see each other. They love each other very much.
They come into ownership of the Decrepit, Moonshadow's old ship, after he loses it. He eventually randomly comes into their shop looking for a new ship and buys the Decrepit back from them for a small fortune.
It is unknown which "twin" is Eloise and which is Poodleoo.
