when your tama is turned away from the screen and has a little bubble floatin gon the side of it's head, that means it's in a bad mood. All you do to get rid of that is to praise it...and then you get one bar of training. Another way is if your tama beeps and there is nothing wrong with it, when it does that you must press disapline...then it gains another bar of training...hope i helped you, pm me with any more questions...
