The titular character is a 40 foot tall gorilla (voiced by Bob Holt) who loves much, he goes bananas! His catchphrase is repeating his name twice ("Grape Ape, Grape Ape") after anything anyone says, usually as a form of agreement or acknowledgement of what was said. He travels the countryside with his canine pal (voiced by Marty Ingels), Beegle Beagle (whom he calls "Beegley Beagley"). Grape Ape's immense size tends to initially shock and frighten those unfamiliar with him, and his presence alone has often terrified people, animals, and even a road sign once, causing them to run off screaming invariably: "YEOW!A gorill-ill-ill-ill-la!"

The show was originally broadcast as one of the segments of The New Tom and Jerry/Grape Ape Show during the 1975
