Chinchillas are pretty smart animals and can pick up behaviors pretty easily - either because it's natural instinct, boredom, or they watch you do something. So what kind of tricks do your chinchillas do (or what kind of tricks do your friends chinchillas do?

My chinchilla, Hermes, has learned to rearrange his cage. The smaller items he picks up with his teeth and carries them around. He can even jump from story to story with them. The bigger items he just pushes off stories and them drags and pushes them to where he wants them.
