  • Patent number: 6682387
    Abstract: A pair of toys or novelty devices for moving relative to the surrounding environment comprises a body for each toy. The body of at least one of the toys or devices to be capable of movement over a surface. A switch with the body activates a magnet to react from one state to another state, and in the second state causing at least one of the devices or toys to move relatively closer together in the surrounding environment. A microprocessor circuit with the body is connected with the magnet such that the switch causes the magnet to operate from one state to another state. When there are a pair of toys, which appear as pets, which get together, and when they appear to kiss each other, there is emitted a kissing sound. Then the cheeks of the pets glow and become red color, resembling the human emotion and reaction.
