Tauntaun

The icy planet of Hoth is notorious for brutal storms that arise quickly with little warning. Temperatures drop below -60 degrees Celsius and gale force winds rip across the ice-covered plains. Luckily for the many adventurers and rebel alliance commanders who voyage to Hoth to see its legendary ice spires, harvest lumni-spice, and make plans to defeat the Empire, one of the best species of animals to cut open and crawl inside to survive a storm in the wild in the entire universe resides there. I'm referring, of course, to the tauntaun. Tauntauns are omnivorous reptomammals approximately 1.5 meters tall with a roomy chest cavity large enough to comfortably hold at least one full grown jedi. But, as Wookiepedia notes, "the most important feature of tauntaun physiology is their unique blood mixture that is resistant to tundra winds and keeps their organs from freezing." Essentially they are extra warmblooded, meaning that crawling inside a tauntaun is a bit like crawling into a hot tub. A hot tub full of, as Luke discovers, stinking "translucent white sausage like innards."
