Zoomer the skidoo is staying with Bob in Sunflower Valley. And, 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 unblock 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 snowbank and gets stuck. Zoomer races off to get help from another machine with caterpillar tracks... Muck! 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!
