So when the valiant cabin boy Tom espies a mound of yellow stuff aboard a nearby ship, the Captain sets off in hot pursuit. Unfortunately, his villainous arch-enemy, the horrible Cut-throat Jake, is not far away. Will the Captain be trapped by Jake's dastardly plan? Or will Tom, the wisest little cabin boy on the Seven Seas, have a plan of his own.?
