An interactive toy (1) comprises stimulus sensors (5) for detecting an inputted stimulus, actuators or the like (3, 4) for actuating the interactive toy (1), and a control unit (10) for controlling the actuators or the like (3, 4) so that the interactive toy (1) may take reaction behavior to the stimulus detected by the stimulus sensors (5). Here, the control unit (10) changes the reaction behavior of the interactive toy (1), according to a total value of generated action points caused by the reaction behavior of the interactive toy (1). Thus, the reaction behavior (output) of the interactive toy is made into points, and the reaction behavior of the interactive toy (1) is changed according to the total value of the points. Thereby, both enriching the variation related to the reaction behavior and prediction difficulty of the reaction behavior can be attempted.
