But I did not take any photos. I could have, especially during the hour or more that I watched him on the trunk of the rose bush. At first, it seemed like he may have been waiting for the 16:45 sprinklers so that he could take a shower. But, as it turns out, he didn't like the water. After a few minutes of being sprayed, he jumped off the rose bush onto the lawn.
I neglected to mention his name. He was กิ้งก่า / Ging Ga. As an English name, let's call him the Oriental Garden Lizard, as Wikipedia does. Color-wise, Ging Ga has some chameleon-functionality. Camouflaged a gray color to blend in with the rose bush trunk, I nevertheless saw plenty of red on his back. Noted, too, was the Mohawk haircut (not really hair...) running down the back of his neck and lower back.
He hit the lawn, and he took off running--standing up. He looked like a small-scale dinosaur as he made great time to the safety of some other bushes. I should like to see Ging Ga run again. It is very fun to watch. I'm sure there are other creatures out there, not just Ging Ga, who think the same of me.
