Who’s excited to explore & learn while having fun in the tub? CoComelon’s JJ (and your little one)! Our special edition collab with the hit YouTube children’s show delivering joyful learning, helps teach floating, sinking and cause & effect at bathtime and beyond (it makes a splash at the beach or pool, too). Just pull the string to wind the propeller and set the sub on an underwater adventure. Check out our entire CoComelon collection for more fun must-haves for playtime, sipping & snacking and more.
