It's the grand opening of the Bobland Bay Promenade. As Bob and the team put up some spectacular lights for the big ceremony, Bristle the street-cleaner arrives to keep the new town spotlessly clean. Before long, important items are missing. It's a mystery, but Bob puts the clues together and they all point to Bristle! Is he really the culprit? Zoomer the skidoo is staying with Bob in Sunflower Valley. When a huge snowfall blocks the whole valley, Zoomer's caterpillar tracks are ideal to help Scoop find his way through the snow with his snowplough to clear the valley. But Zoomer is impatient and easily distracted. When he sees a distressed little rabbit he leaves Scoop on his own. With no expert guidance, Scoop drives into a deep snow bank and gets stuck. Zoomer is very sorry. He was only trying to help the little rabbit, but Bob has a great machine-inspired idea to help the animals!
