This entertaining PBS series combines the comedy of a cartoon, the challenge of a game show, and the excitement of reality TV. The star of the show is slightly high-strung but lovable cartoon canine Ruff Ruffman, who presides over the activities from his state-of-the-art "headquarters" -- aka his doghouse -- which is equipped with the high-tech FETCH 3000 computer. Ruff communicates with the contestants either by video or phone, doling out assignments, monitoring the contestants' progress, and throwing occasional twists in the works to make the assignments more challenging. Every so often, Ruff will have a minor -- and rather amusing -- nervous breakdown as he pretends he's cracking under the pressure of producing and starring in the show.

The challenges are interesting and engaging -- as well as enlightening -- and the young contestants (real kids, not actors) are bright and enthusiastic. This is no mindless reality or game show; some of the clues are quite difficult, and the kids have to use real-world science knowledge to conduct experiments and complete tasks. It's a great way to add an educational twist to the excitement and competitive aspect of a game show, and the cartoon segments featuring the funny, neurotic Ruff add a whole new wacky dimension. Fetch! is a truly original series that's great fun to watch -- especially for young viewers interested in science or anyone who loves a good scavenger hunt.
