Golden hamsters, also known as Syrian hamsters, are flexible little creatures that can crawl through plastic and underground tunnel systems alike. In this video from Nature on PBS, we get to watch one navigate sharp turns and u-turns within his hamster tubes. X-ray video of his movements illuminates how his body manages the tight spaces.

Then see how the little guy stores food in his gloriously stretchy cheek pouches… a lot of food… like, really, a lot. He seems to be storing food as if he won’t find more for a long time, a trait that would serve him well in the wild. According to Smithsonian Magazine, their Arabic name translates roughly into an endearing one: Mister Saddlebags.

Watch more skeletons, and more super cute videos.
