The series was initially co-hosted by Alan Hamel and Michele Finney,[1][2] later replaced by Ray Bellew and Trudy Young.

There was also a cast of characters who appeared in every episode, most notably the puppet Howard the Turtle (John Keogh), who was considered the star of the show.

Other recurring characters on the show included Howard's nemesis, Percy Q. Kidpester (Ed McNamara / drawn by George Feyer); conman and travelling salesman, Mr. Sharpey (Paul Kligman) who was known for saying "A knuckle full of nickels" and the general store proprietor, Mr. Igotit.

Another regular feature was the serialization of a children's adventure series in the final five minutes (thus spreading each episode over a week's worth of shows).

He went on to have a long career in Hollywood winning an Emmy for The Bill Cosby Show.
