Baby Shark has his first loose tooth! But when he gets overly excited to trade it in for a sweet, sweet sand dollar, Toothy is lost in the Water Warps! So Baby Shark and his best friend William set off on an adventure to find Toothy before it's too late. Baby Shark and William learn an important lesson about patience--and make a new friend in the process--in this fun, interactive board book with a snapping, plastic Baby Shark head!
