Encouraged by Bert, the cat, Murdoch Mole believes he has done all sorts of things he couldn't possibly have done. When he discovers his 'biggest molehill in the world' was actually made by a bulldozer, his self-esteem takes a nasty tumble. His friends rally round, and he is soon back to doing what he does best, digging tunnels - a very particular tunnel under the road so that toads and other small animals can cross in safety. Stunning illustrations.
