uuh she doesn't have a name. He wasn't really given a name. He lives in the forest and takes care of trees. The eye on her forehead helps her navigate, since her other two eyes are rather undeveloped.
Sometimes pine leaves get in his eyes and it's really bothersome.
She doesn't have arms or he does. I dunno.
His bones are hollow like a bird's, but she cannot fly. But that's why she is so light.
