You know what...I've seen Zoe doing the "I'm a leaf" walk PLENTY of times! I can assure you, he was NOT trying to walk! He was staying in one place, and rubbing himself on me. He was quite aggressive about it. I can tell you this...I may not know much about chams in general...but I know MY cham, and what he looks like when he's walking...Thank you very much!
:He was probably just moving forward and back right? He was most likely mimicking a leaf blowing in the wind, which helps them blend in. Maybe if you knew anything about chams you'd realize this.
