Our Little Loch Ness Monster

This is Bentley, our ornate box turtle. My son calls him "Feisty Pants" because he loves to bite your fingers! Lately, he's decided he's a Loch Ness monster and spends all his time in his water bowl. Every couple days I kick him out and change the water so it doesn't smell like a cess pool. Then he pouts and refuses to get back in it.
