Wampa ice creatures were carnivorous predators indigenous to the remote planet Hoth. The bipedal beasts stood over two meters in height with shaggy white fur constantly stained by the blood and guts of slaughtered prey. Wampas were armed with jagged yellow teeth and deadly claws. Primarily solitary hunters, wampas occasionally hunted in packs, preferring to ambush their prey from the camouflage of Hoth's snow banks and blizzards. Stunned victims were carried back to the creatures' lairs, typically large ice caves, where the wampas ate at their leisure. The planet's omnivorous tauntauns formed the bulk of the wampas' prey, although they would attack anything they encountered. The Rebel Alliance's Echo Base on Hoth came under constant wampa assaults in 3 ABY.
"The kid ran into something, and it wasn't just the cold."
―Han Solo, referring to Luke Skywalker's wampa attack
