Mary Ann and Louie are back, to let Grandpa top their difficult situation yet again; this time they're taking care of the Murphy's dog, but when Grandpa and his brother Wainey, years ago when they were small boys, agreed to feed the neighbor's cat, they were trapped in a Herculean task. So begins one of Stevenson's funnier tall tales. The two mustached tots are responsible for turtle, cat (well, a whole roomful of cats), parakeet, gerbils, hamster, rabbit--you name it. Escapes, rescues, and disasters are the order of the day. But when watering the greenhouse takes too long, Grandpa invents a remote control Rube Goldberg to handle his tasks from a distance, and after a final bit of mayhem. all returns to normal just in time for the neighbors' return. Stevenson's expressive, comically suggestive line keeps the story rollicking along; the cartoon-balloon text is less distracting than in some of his recent books: visually, the illustrations take priority, as they should. Fun.
