My girl Pancake would soak in her water bowl a lot too last Winter! Her temps/humidity were spot on and she didn't have mites but for almost two months straight she'd just lay in her water dish. Sometimes she'd submerge completely and it scared me a bit. She stopped doing it though. Now she just likes to stick her head in and blow bubbles. She also like to watch TV with me and will do the cobra pose to get a better look at it. XD
