Sprocket, Dog Detective is a Fraggle Rock storybook. It centers on Sprocket, and how one occasion, intrigued by his brief glimpses and contacts with Fraggles, he decides to follow one such Fraggle: Uncle Traveling Matt. As Matt explores outer space, Sprocket decides to follow him. They both see the 1943 movie Lassie Come Home, and both react to the screen (alarming the theater manager). The pair make friends, overcoming Matt's previous fear of the "Beast," and when Doc finally returns, he finds a dog satisfied by his exciting day.
The book was also published in a non-Weekly Reader format as Follow That Fraggle!
