'The Stroogle Sails the Seven Seas begins when the Stroogle discovers an old pirate's map in a bottle. Together with his two friends, Gretel and the mouse, the Stroogle sails off on a raft in search of buried treasure. Along the way he meets the dreaded Pie Rats and after a skirmish onboard a giant pie ship, he is ordered to walk the plank. Luckily Grandpa Garden Gnome arrives just in time to rescue them in his new submarine. The journey continues underwater, in a cave, through a pie fight and off to treasure island.'
