Mine does the hangs out in his burrow and watches me. Other then feeding time I hardly see him but he sees me lol. Sometimes he'll be out and a out then back to his home. I think that's what they do. They find a nice spot and just pop out to watch you. If I get to close or try and snap a pic he shoots back in his home. He even put old snail shells around his burrow.
