Baby will love to explore the soothing textures of Cal’s antennae or create some noise by shaking the hourglass beads to create rattle sounds. For cause-and-effect discovery, infants can twist Cal’s head to make a clicking sound or use the baby-safe mirror on the toy’s base to promote self-discovery and delight. 4 rattle rings encourage fine motor skills or help parents teach color learning to toddlers. High contrast colors stimulate baby’s visual development, and two easy-to-grasp handles make this battery-free toy a perfect way to engage baby on-the-go. Directions Shake the rattle to make noise and explore its sensory elements.

Review: Charming and Educational — A Hit with Babies and Parents! - Outstanding Opus The Octopus by Baby Einstein is such a charming toy that captivates babies with its bright colours and engaging features. The soft, plush design makes it perfect for cuddling, while the interactive buttons introduce little ones to fun sounds and music that stimulate early learning. My baby immediately loved exploring Opus’s tentacles and pressing the buttons to hear different melodies and phrases. It’s durable and easy to clean, which is always a plus with baby toys. This toy is both entertaining and educational, making it a fantastic addition to any baby’s collection. A wonderful gift choice for babies and toddlers alike.
Review: Soft crinkly fun. - Fantastic crinkle cloth book for babies. The handle is a safe teether for babies, and the soft fabric pages “crinkle” in baby’s hands. The book can also be machine washed over and over again. I bought this for my granddaughter when she was born, she’s now four, and this is one of my “go to” new baby gifts. Would definitely recommend.

### ⭐⭐⭐⭐⭐ A Musical, Tentacle-Wiggling Hit!
*by E***3 on 4 April 2025*

Outstanding Opus really lives up to the name! This adorable octopus has been an instant favourite—the music is fun and engaging, and each tentacle plays a different instrument, making it a great intro to musical exploration for little ones. The sound quality is surprisingly good, and it’s the perfect mix of education and entertainment. My baby lights up every time Opus starts playing and loves pressing the buttons (over... and over... and over again 😂). Bonus points for volume control! If you're looking for a well-made, interactive toy that encourages sensory play and musical discovery, this little octopus is a winner.
