Robert Louis Stevenson

A sixteen-year-old orphan is kidnapped by his villainous uncle, but later escapes and becomes involved in the struggle of the Scottish highlanders against English rule.

When young Billy comes to possess a secret treasure map, he sets sail with mild-mannered Capt. Smollet and a host of assorted Muppets and humans in search of the wealth. Their adventure is filled with songs, wacky humor, and irreverent silliness.
