Excited they arrive at Mrs Woodmouse s house licking their lips at the sight of the delicious Christmas pudding that s cooling on the window ledge. But, oh no! The pudding s been pinched by a rat called Pogue and his gang of rogues. So off they set in hot pursuit, following the rats trail of crumbs down the rats dark tunnels where Malcolm s talent for seeing in the dark saves their Christmas Day!
