Indiana Bones and the Invisible City

As the slithery Serpent reveals his plan to plunge the world into peril, our hairy hero and his pal Aisha are in a race against time to unravel the clues to stop him. Not even six million skeletons and an invisible enemy can stop these brave badgers! Or can they? Because Indiana's mind is on something else - and unless his friends can help, they'll all end up in very deep water . . .
