I wish I'd taken a photo to share, but my G pulchra often has it's butt up in the air at a comical angle in a defensive posture it adopts if I'm doing anything to the nearby enclosures.
However, it ate a rather large superworm the other night, and was looking extremely fat. As I was replacing it's next door neighbour on the shelf, the pulchra caught my eye and I burst out laughing. As usual it had assumed the position and a very fat bum was pointing right at me. What was different was that it was using its cork bark to prop up and rest the weight of this massive butt. Obviously it's short little legs weren't up to the job!
