You mean moving around the screen? They always do that. Dancing is an animation. To figure out if it is dancing or just moving around the screen, press the A button. If it stops, then it is an animation. If it doesn't do anything, then it is just moving around the screen
no! this is so not normal at all!! ichigotchi does dance but not when he is hungry!! you might have to reset it otherwise i can't help but this helped bye!!
