An image displaying apparatus stores plural image data and displays one of the image data, which image data represent a growing plant (animal) or represent a series of motions of an animal. The apparatus further stores plural element data for growing the plant (animal). When one of the element data is selected, another image data of the plant (animal) is displayed in place of the previously displayed imaged data to show how the plant (animal) grew up responsive to the selected element data. The apparatus is provided with a sensor for detecting motion of a user. Detecting the motion of the user, the apparatus displays new image data representing a motion of the animal in place of the previously displayed image data to show how the animal reacts to the user's motion.
