Galactic Galaxy Space Unicorns

Where did Unicorns, Pegasus', and Alicorns really go?
Space!
But they're going extinct!
A space agency has been put in charge of the only known herd of Unicorns, Pegasus', and Alicorns in space and are supposed to bring the unicorns back to a stable population (pun intended).
However, there's a group of people called the Darkicorns who can only think of hunting and selling the horns, wings, and hides of these majestic creatures.
The Galactic Galaxy Space Unicorns (or G.G.S.U. For short) will do their best to protect the Unicorns and destroy the Darkicorns.

A super goofy story that I hope manages to make you laugh
