I was thinking about how Gen 6 Pixelmon are going to be added when Gen 7 is out, so.. I thought about making a tree for Xerneas and some Fairy Types!
Xerneas would be standing on the wood of one of the sides of the tree. Not all of the Pokemon spawning are the ones that would be changed to Fairy Types with Gen 6 Pixelmon.
There is a PokeLoot hidden inside the tree that has a Fairy Gem in it, and there's a Moss Rock near the tree.
(Did I do this right?)
