Howdy, Partner! Fred might need to trade his ascot in for a bandana when he and the rest of the Mystery Inc. gang — Velma, Daphne, Shaggy and, of course, Scooby-Doo — head for the Wild West in this collection of fun, themed episodes, including “Mine Your Own Business,” “Go West, Young Scoob” and “Bum Steer for Scooby.” So giddy up and get ready to guffaw. Scooby-Doo! Wild Wild West is waiting.
