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 sit at play. The otter comes with a soft book that features high contrast colors plus a self-discovery mirror and crinkle panel to stimulate baby's developing senses. During tummy time, position the book's mirror on the otter's back for 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 perfect size for on the go fun too!​
