It’s the timeless story of wolf sees lamb, wolf chases lamb, hound pummels wolf, wolf loses lamb. In this case, Mildew chases Lambsy in every location possible, only to get clobbered by Bristle Hound. It was originally a segment of The Cattanooga Cats on ABC, then it became the middle feature of Motor Mouse the next season when that show broke off from Cattanooga Cats.
