Oh and a one-armed wampa. I dunno how long those live.

Wampas were even said to possess, at least in one case, the capacity to retain long-term memory.^[15] During the Rebel Alliance occupation of Hoth during the Galactic Civil War, Jedi Luke Skywalker was attacked by a wampa while patrolling the planet's ice wastes, but he escaped the creature's clutches after slicing off its arm with his lightsaber. Almost a decade later, during a return visit to Hoth, Skywalker re-encountered the same wampa whose arm he severed years before.^[1] Skywalker claimed that the one-armed beast remembered both him and his lightsaber.^[15]

But I dunno, I suspect the Wampa just pretended to remember Luke so things weren't awkward.

LUKE: Wampy! Hi there!
WAMPY: Uh, hi....you...
