I used to have one of these back in college. On winter break, I couldn't take it home with me so I left it in the bathroom with plenty of food. Little did I know that the campus turned off all heating and electricity to the dorms during the winter (cold NE winter). I came back to a frozen little bugger. I was being lazy and didn't flush it/throw it out for a couple of days. Good thing cuz I guess it thawed with the room temperature and came back to life.
