First there was the nice old beardy guy. Every one loved him, young or old, except for one man, His Son (The young captain in the submarine) !!! He coveted his fathers role as captain Birdseye, and together with his evil Stork companion, Pedro plotted to take over the captains wheel. He soon found his chance.
After the original captain launched the controversial campaign of spiriting kids away to the antartic to perform a quest in order to recieve the capains fish fingers, his son struck, flooding the media with anonymous tipoffs of paedophillia scandal. After the original captain was convicted and executed for buggery, thanks to some evidence, falsified by Pedro. His "grieving" son took over the helm.
But his reign was short lived thanks to some cunning detective work by the original captains long lost brother, who unmasked the villainy of his nephew, who was disgraced and reduced to attempting to steal fish fingers from children living on a desert Island. The only man who can stop him is his good uncle who took over the helm of Captain Birdseye. Good now prevails. But for how long?
