Pint-sized swashbuckler Capt'n Sharky thinks he's the most dangerous pirate on the Seven Seas. To prove his bravery, he sets sail with Mikey, a well-behaved boy whose life Sharky has turned upside down, and Bonnie, a trouble-shooting girl who tends to assume command in every situation. Together, this motley crew sails for big adventures as they thwart the plans of The Admiral and Old Bill the Pirate?
