The Funmuch Musical Hedgehog Projector Toy is a soft companion designed to soothe infants from birth. This grey plush doll combines the functions of a musical toy, a night light, and a projector that casts a starry sky onto the ceiling to help your baby drift off to sleep. Wrapped in soft cotton fabric, the hedgehog weighs 600 grams and feels gentle against a child's skin. To create a calming environment, you can choose from various sound effects, including white noise, the sound of surf, a heartbeat, or singing birds, accompanied by relaxing melodies. The device runs on three AAA batteries, which are not included, making it easy to place anywhere in the nursery without worrying about cables.
