Funny Lizards

One day when I went to the library, while we were singing some songs, I glanced at the lizards' cage. There was one on a log. He was bobbing his head up and down like he was nodding, except his nose was always pointing forward. When I got to the lizards cage, he looked normal. He walked around the tree trunk and sat and stared at me. I stared at him too. When I got back to the cage, he was scratching at the glass like he was trying to go through it or climb. It was funny. And when I imitated him, acting like I was climbing, he cocked his head to one side, wondering where were my scales.
