"The Jim Henson Company Presents "The Sam Plenty Cavalcade of Action Show Plus Singing!" is a live action web-series from the Jim Henson Company. The series was created and directed by Paul Rugg and Mitch Schauer. The show is an over-the-top tongue-in-cheek parody of classic television serials. The first serial in the "The Sam Plenty Cavalcade of Action Show Plus Singing!" was entitled "Sam Plenty in Underdoom". The first installment of the five-episode serial debuted on the web on March 10, 2008 (although adding the parody element, the episodes begin at "part 3").
