Mr. Putter and Tabby are hot as there seems to be no escape from the weather, but then Mr. Putter decides a trip to the lake might be quite refreshing. He invites his neighbour Mrs. Teaberry and her dog Zeke. They have a great time rowing to a shady spot and picnicking. But after a walk back home, they are just as hot as before. Mrs. Teaberry comes up with a cool, wet surprise. It's a delightful easy-to-read story that presents grandparent-aged characters in a positive light, having lots of fun.
