Wild Growth is kind of an exploration of the Kaldorei transposed into Equestria. In my imaginings, they keep their height and their elven long ears. Being primarily nocturnal, their coats would favor darker colors, especially in shades of purple, blue, and green, to better blend into the forests they call home. Their eyes would, of course, retain the whole glowing thing, and I still see druids among them, like Wild Growth, working in nature both to preserve the balance of their home and to ensure stable food and housing.
