Wampas
Wampas are primitive, extraterrestrial creatures indigenous to the ice planet known as Hoth. Towering at more than eight-feet-tall, they are powerful, predatory carnivores that live in caves and hunt for live prey. With the aid of the white fur, a Wampa can easily camoflage itself in Hoth's snow-covered terrain, making it easier for the creature to stalk its prey. They will use their massive paws to snap an animal's neck then bring it back to the cave where it will either eat it right away, or save it for future consumption. In 3 ABY, Rebel Alliance leader Luke Skywalker had a grisly encounter with a Wampa. The creature attacked him while he was planting sensors in the area and killed the Tauntaun he was riding. It dragged both Luke and the dead animal back its lair. It suspended Luke upside down from a frozen patch in the ceiling of the cave, intending on preserving him for later. While the Wampa dined on the carcass of the Tauntaun, Luke used his lightsaber to cut himself free. The noise alerted the Wampa who charged after him. Luke swung his saber, severing the creature's arm, then made his escape out into the bleak, snowy landscape.

Wookiees
Wookiees are an arboreal race by nature, preferring to live in small tree huts than on the ground. They communicate through a complex system of grunts and growls, which often leads others to mistakenly believe that wookiees are primitive and savage, when in fact, they are an extremely intelligent species despite their fearsome appearance. Wookiees are known to have a longer life span than most other races and wookiees in the prime of their life are sometimes more than two-hundred years old. Wookiees cherish life and have a strong sense of respect with regards to other life forms. Once every three years (Kashyyykian calendar), wookiees celebrate a festival known as Life Day. The holiday is a time of rebirth and renewal in wookiee culture and it celebrates the life-cycle of the planet itself. Regardless of one's location, a wookiee was expected to be at home with their family so as to honor Life Day and pay tribute at the Tree of Life. Another important element of wookiee culture is known as the Life Debt. If a wookiee's life was saved through the actions of another, whether they be wookiee or some other alien species, the wookiee in question was honor-bound to serve them as guardian and friend, even to to the point of sacrificing their own life if need be. As the title implies, the wookiee is obligated to observe the life debt for the entirety of their savior's lives. In many cases, the life debt may be extended to include their savior's loved ones, friends or family members. Other alien cultures practice the institution of the life debt including the Gungans of Naboo and the reptilian Trandoshans.
