Armadillos collect leaf litter that they use to build nests in their burrows. Because carrying is difficult when you're shaped like an armadillo, the animals opt for bunching a pile of leaves up against their abdomens and kind of hopping backwards toward their hidey holes. And all of that is a sciencey introduction to this video of an armadillo dancing to Michael Jackson's "Billie Jean".
