Ratatoskr

Sometimes Arvid and Nidhogg have things to say to each other, and so they employ the help of the squirrel Ratatoskr to travel up and down Yggdrasil, The World Tree to deliver insults and information from eagle to Serpent and serpent to eagle.

Appearance

Ratatoskr is a giant red squirrel, a common species in Europe, which shape shifts and changes size with magic. He prefers to take on a more maroon hue than red or brown fur, and likes to enlarge his fluffy tail and ears to twice their size. He usually travels up and down the tree in a form smaller than The Bark Serpent, so he can navigate his way around the Serpent.
