Relative to their size, the cru had two very large ears and a large nose. Black stripes were located on the back head. Cru also had jagged wings that were used for flying. On their wings, one sharp claw was located on the top of each wing. The cru also possessed a long brown tail relative to their size. On each foot, a cru has two toes. After a meal a cru would fall asleep.
In 232 BBY a cru named Cham Cham was the pet of the Force-sensitive, Zeen Mrala. Cham Cham was with Zeen when the Nihil launched an attack on the planet Trymant IV. During the attack Grand Master Yoda used Cham Cham to help locate Zeen's friend Krix Kamerat.
