An apparatus includes a movement mechanism, a sensor, a microphone, a speaker, a processor and a memory. The processor selects a target region, controls the movement mechanism to cause the apparatus to move to the target region, and causes a speaker to output a first sound. When counting a predetermined number, the processor causes the sensor to trace a movement locus of a user. In a case where the processor has determined that an acquired sound contains a predetermined speech, the processor controls the movement mechanism to cause the apparatus to move through a predetermined space. When the processor has determined that the apparatus is not to intentionally lose in a game of hide-and-seek, the processor controls the movement mechanism to cause the apparatus to move to a target blind spot within the predetermined space, and causes the speaker to output a second sound.
