This versatile baby gym from Baby Einstein takes your little one on a voyage of adventure with lights, music and learning-inspired activities. The jumbo-sized baby mat leaves plenty of room for you and your baby to play together. Every quilted scene introduces new colors, shapes and underwater friends. Take a closer look for surprises to discover and explore, like peek-a-boo flaps, crinkle textures and hidden pockets. The crab-shaped prop pillow is perfect for tummy time, giving your baby a whole new view of the world. You can flip up the sides and attach to the play gym to keep your busy baby where they need to be. Or create a secret passageway with a crawl-through tunnel. When baby grows, fold the mat in a few simple steps to create a giant plush storybook for you and your toddler to enjoy.
