Harry the dog is very hot. All he wants is a shady spot away from the sun. But there’s no more room under the family’s beach umbrella or anywhere else he looks. So Harry sits down sadly at the water’s edge. Suddenly a big wave crashes over him, and when the wave rolls back, Harry is completely covered with seaweed. Now he’s nice and cool, but everyone on the beach thinks he’s a sea monster. On top of that, he can’t find his family anywhere.
