Charles Nelson Reilly, already a fixture on the CBS version of Match Game, was the crocodile-suited star of this three-month Filmation series on ABC, a parody of the Animated Anthology programs with live presenters that were in nearly every major TV market in the 1950s and 1960s. Reilly's co-stars were Alfie Wise as Uncle Croc's sidekick, Rabbit Ears, and Jonathan Harris as the director, Basil Bitterbottom.

"Who's our Star Time guest for today, Uncle Croc?"

The three animated segments were:

  • "Fraidy Cat", about a nervous alley cat visited by the ghosts of his eight previous lives;
  • "M-U-S-H", a canine parody of M*A*S*H whose title expands to "Mangy, Unwanted, Shabby Heroes", and
  • "Wacky and Packy", in which a caveman and his pet mammoth are transported to 20th-century New York.

Live-action segments included "The $6.95 Man".
