The Wombles have just gratefully returned to their burrow on Wimbledon Common. They had needed to leave because heavy lorries thundering up and down the nearby road had threatened to make the roof of the burrow cave in.Now that the Wombles are safely back, though, there is another problem they have to contend with. It seems that the humans have realised they have an energy crisis and are throwing much less away. The Wombles' supplies begin to run low. What can the Wombles do? It is time for EMERGENCY SPECIAL PROJECTS - with DIY king Tobermory in charge!
