The Wombles live in a beautifully snug, well-ordered and cosy burrow underneath Wimbledon Common - the perfect base from which to sort and recycle all the rubbish that unthinking humans constantly drop. But the Wombles peaceful and harmonious existence is suddenly under threat. The heavy lorries that thunder along the roads near the Common make the burrow shake and tremble so much that it is no longer safe for the Wombles to live there. With a heavy heart, Great Uncle Bulgaria decides that the Wombles will have to move from the burrow that they have lived in for many, many years. And it is up to young Bungo and Orinoco to bravely sally forth and try to locate a new home for the Wombles . . .
