The Baby Einstein Neptune’s Ocean Discovery Jumper gives your baby 360 degrees of engaging activities with a splash of underwater wonder. Your mini marine explorer can embark on a playtime expedition and swivel from toy to toy in the height adjustable baby bouncer. There is a crab that spins inside a clear ball, a little starfish that holds a self-discovery mirror, an octopus paddle toy, and flash cards with real underwater imagery to boost vocabulary. The removable sea turtle activity center helps your baby discover numbers and colors in 3 languages (English, Spanish, and French). With extra link loops, you can also add your baby’s favorite toys or swap out fresh ones for a new ocean of discovery. The baby bounce chair allows your little one to jump and dance, which helps strengthen their developing leg muscles. With no doorways required, you can watch your baby safely play and grow wherever you need to be. Use the activity center only if the child can sit up unassisted and is less than 30 inch tall. Weak batteries cause erratic product operation, including distorted sound. Because each electrical component requires a different operating voltage, replace the batteries when any function fails to operate.
