Hahaha! I have noticed Azure cruise around her vive, and she sometimes keeps her back legs tucked in to her sides while her front legs pull, and she looks like an alligator moving herself around. Or like she's trying to swim on land. It's too funny! I know the back legs work fine though, because she moves quick when she wants to and clambers all over the decor in her vive too!
yup mine do the same thing. They really are pretty interactive and fun lizards to watch. I end up sitting in my office just watching both of them while I wait for my Tegu to eat.
