Discover the Opus's Ocean of Discovery Water Mat from Baby Einsteins with your baby. Simply fill the center of the play mat with water and inflate the outer edge with air. While playing in a seated or tummy position, your baby can work on muscle development while moving the six floating sea creatures beneath the surface. Perfect for curious children from newborn age. This practical activity introduces the concept of cause and effect as babies touch the mat and watch the underwater creatures swim. It helps keep infants and toddlers engaged while promoting the development of gross motor skills. Cleaning is easy: just drain the water and air, wipe down the mat, and fold it for storage or transport. Use the mat at home or take it on adventures so your baby can explore the underwater world with all their senses anytime, anywhere.
