A Warm Rock is a Joy Forever

A Nile Monitor Lizard; these climb, swim, and burrow, but being lizards they also bask with devotion. Just out of the cropped frame is one end of a large ABS pipe, carefully painted to look like bamboo. It has one closed and one closable end, and it's used to feed the lizard, since that way it's used to crawling into the pipe which makes transporting the lizard every so much easier.
I certainly wouldn't want to have to pick up even a torpid Nile Monitor this size.
