There is now a fifth drive for Creatchi called Energy. If a Creatchi's energy level falls too low, it will start to complain that it's getting sleepy. When this occurs you can put on the Creatchi item "sleep mask" and the Creatch will go to sleep. Once it's done resting, it will wake back up feeling better than ever. Sleeping Creatchis cannot be given items or socialized with.
I like it . You can 'tuck' your Creatchi's to bed when you need to get off. It's kind of comforting to know that, and it makes it a bit more realistic!
