Gentle vibrations are what make this teddy bear so unique. Its heartbeat's vibration is activated when the teddy bear is hugged. This cuddly bear is covered in a soft, velvety fabric and filled with memory foam. Cuddle Cub's tactile sensations are carefully chosen to comfort, calm and provide a sense of security to children of all ages. A unique heart shaped vibration unit is tucked safely into the body to provide two gentle vibration options. The hug mode activates a gentle hug timer which shuts off in 2 minutes. The heartbeat vibration has a continuous motion that will soothe any restless sleeper. Requires 2 AA batteries.
