What's puzzling me is the size of it, I can't compare it to anything in the picture. If I compared it to the tree, that would just be ridiculous seeing as the tree is 2x wider then the pokemon itself. I could be wrong though, this may be an extremely small legendary. Someone fill me in?
Yggdrassil theory. The Tree of Life, Yggdrasil, has four animals associated with it. A HAWK, a squirrel, a dragon, and a STAG. But wait, there's more. As is visible in the trailer, the tree by Xerneal is massive. A giant tree? Gee, that sounds like YGGDRASIL.
