This rattle features an easy-to-grip puppy design that produces a rattling sound when shaken, accompanied by colorful beads inside. The puppy's cheeks light up when moved, demonstrating cause-and-effect relationships for young children. A music button activates over 20 songs, melodies, sounds, and phrases for auditory engagement. The toy includes crinkly ears for visual and tactile stimulation, along with two textured rings that rotate and rattle to support motor skill development. It operates on 3 LR44 batteries (included for demonstration; fresh batteries recommended for continued use). Suitable for children aged 3 months to 2 years.
