He's learning how his beard works. When Rubio, who's now 3 yrs old, first discovered that not only could he puff his beard but he could turn it black, he was almost cross-eyed with effort, puffing it out up & turning it sort of black for days on end. He was just a bit older than your beardie. It's the beginning of figuring out he's male! And it's really funny to watch!
