Well, I got lots of things to collect more but I recently got the undead KaKao(Latte) dragon, and frame dragon. 

If you guys want to take a look at it and then come to my village, I'm in the east asian server, and my nickname is 사토 유키. 

 Every undead dragons has their own story. Try using the translator inside the game and check it out!

Oh and I'll just gonna add slight warning on it. I usually add a dot image on my village with tiles and it's gonna be somehow cruel.
