Question: What title did Krofft Productions give the remake of their half-hour Saturday-morning children's series?

Context paragraphs:
Paul Reubens: Paul Reubens (born Paul Rubenfeld; August 27, 1952) is an American actor, writer, film producer, game show host, and comedian, best known for his character Pee-wee Herman.  Reubens joined the Los Angeles troupe The Groundlings in the 1970s and started his career as an improvisational comedian and stage actor.  In 1982, Reubens put up a show about a character he had been developing for years.  The show was called "The Pee-wee Herman Show" and it ran for five sold-out months with HBO producing a successful special about it.  Pee-wee became an instant cult figure and for the next decade, Reubens would be completely committed to his character, doing all of his public appearances and interviews as Pee-wee.  In 1985 "Pee-wee's Big Adventure", directed by the then-unknown Tim Burton, was a financial and critical success, and soon developed into a cult film. " Big Top Pee-wee", 1988's sequel, was less successful than its predecessor.  Between 1986 and 1990, Reubens starred as Pee-wee in the CBS Saturday-morning children's program "Pee-wee's Playhouse".
