The otter-ly adorable 2-in-1 Rockin' Tummy Time Otter plush sensory toy from Fisher-Price grows with your baby from tummy time to sitting at play. The otter comes with a soft book that features high-contrast colors plus a self-discovery mirror and crinkle panel to stimulate the babys developing senses. During tummy time, position the books mirror on the otters back for the baby to see themselves. When your baby begins to sit up, the otter transitions to become a fun roly-poly toy that rocks back and forth and makes a fun jingle when baby bats play. Both the book and otter are the perfect size for on-the-go fun too!
