DJ has learned a new trick. He stands on the perch in front of his happy hut with his back to the opening. Then he'll lean back until he's lying on his back in the hut.
He keeps his feet on the perch though and after a few seconds he just stands back up!
He also likes to lie in it with his head sticking out and hanging down like he's dead. Scared the crap out of me the first time I saw that!
