This isn’t our bearded dragon, but the action is exactly the same. At first we thought Remington was doing it because he was perched right under the heat lamp and the log was hot, but apparently it’s a form of communication – though no one is quite sure what they’re trying to say.
So one time I went to the grocery store and after I paid for my groceries I stood waiting for the cashier to hand me my receipt. I waited for several minutes, in fact, until he informed me that he had already given me the receipt and I’d put it under the grocery bags in the cart.
Luckily the person behind me was a girl from my ward, and she didn’t mind.
