cydonia castle
dark wood tral at pbolnia
You can find it at Cydonia Castle on Sunshire. It's very rare, so you must be patient and you will need 10-20 starseeds.
You can find monster galaxy in Myspace or Twitter
I found mine in Spiral Cave, but I haven't found but one, sorry.
First go to cydonia castle and find a spike. Second battle with spike and make his health less than 30. Then just use a starseed. If your lucky you can catch it with only 3starseed. I used 4starseed. Good luck.
