Come on, you all knew it was coming. With the new space flowers, and the space dragon... I couldn't resist.
So, Spaceflower Dragon!
They originate from a lifeless asteroid belt, and once they grew large enough, left to explore the universe. They discovered flowers as they flew through the galaxies, and was enamored. Now, whatever planet the visit, they bring along with them a blooming souvenir, kept alive in the void of space by magic.
