When Kayla's favorite dolphin floatie loses its air at the beach, she wants to just sit on the sand. Daddy calls for her to play with him and her brother in the surf, but the DEEP BLUE SEA gulps sand out from underfoot, and a wave knocks her down, sending water up her nose. "I want to go home," Kayla says. "I can't swim without my dolphin." But Daddy reminds her that she knows how to swim and even how to hold her breath underwater. He hoists her up on his shoulders and wades into the sea. "You be the island," Kayla says. "I'll be the lighthouse." In a charming sequel to Wild Blue: Taming a Big-Kid Bike, author Dashka Slater and illustrator Laura Hughes take on another milestone moment, showing that with patience, a parent's easygoing support, and a creative mindset, a child can gain the confidence to tackle a daunting new experience--and grow from clinging to a dolphin floatie to swimming through the ocean just like a dolphin!
