Penfold's overenthusiastic cleaning leads to the collapse of the World Wide Web and the awakening of the long-forgotten gigantic World Wide Spider. Tackling this ginormous arachnid ought to be a simple job for Danger Mouse, but our hero has been nursing a secret fear of spiders! With the help of Penfold, the Taj Mahal and the vacuum of space, DM must face his fear, defeat - and then dispose of humanely - the gigantic 8-legged beast that is threatening to eat the world.
