Cook is a lean wolf with an average build, reaching about 29in tall and 5.2ft long, weighing in at around 90-92lbs depending on how long he's gone without eating. His pelt is a light brown, with some grey mixed in; it can seem to change colour depending on his location - in the forest it is darker, the colours bringing out the brown in his coat while in the winter, the white of the snow can bring out the grey. His eyes are a striking, light amber and are usually dancing with light due to his good humor.
