The new branches then reach out in all directions to find other branches to join with. This tendency towards unity makes wroshyr trees incredibly strong and it is also a natural symbol of the Wookie concepts of honor and family. Wookies are covered by thick, soft fur. Usually, the fur is either brown, black, gray, or silver. There can be variation in shades, or combinations of colors.

They are quite tall, with the average height of and adult Wookie ranging from 2.0 to 2.3 meters. Also, Wookies are very strong, this is attributed to the fact that they must rely on their own power to travel among the giant wroshyr trees. While there is no data to quantify their strength, they are capable of ripping someone's arm out of its socket. The claws are quite large, curved, and hidden in fingertip sheaths. Even though Wookies have a rather primitive appearance, they are highly intelligent and quite comfortable with technology of all levels.
