The first animated series ran on Saturday mornings from 1973–1975 on NBC. In a departure from the original series, this series took the Addams' on the road in a Victorian-style RV. This series followed the relationships of the original Addams cartoons in that Fester is Gomez' brother, and Grandmama is Morticia's mother. Many cast members from the original series and the Scooby-Doo episode reprise their roles in the series, with the exceptions of Astin and Jones whose characters were voiced by Lennie Weinrib and Janet Waldo. The show also introduces the Addams Family's animal companions Ali the Alligator and Ocho the Octopus.
The theme music was mostly different, except for the four-noted tune from the live-action series.
