Cap'n Crunch, canine first-mate Seadog and a crew of four kids had to always think fast to keep the Guppy's crunchy cargo out of the hands of the scheming yet bumbling pirate Jean La Foote, who always went barefoot. The character was liberally based on the historical figure of Jean Lafitte, the notorious privateer who raided the Louisiana coastline in the early days of American independence.
