Scooby-Doo, Where Are You! made its CBS network debut on Saturday, September 13, 1969 with its first episode, "What a Night for a Knight." The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, radio DJ Casey Kasem (later host of radio's syndicated American Top 40) as Shaggy, actor Frank Welker (later a veteran voice actor in his own right) as Fred, actress Nicole Jaffe as Velma, and musician Indira Stefanianna Christopherson as Daphne.[14] Scooby's speech patterns closely resembled an earlier cartoon dog, Astro from The Jetsons (1962–63), also voiced by Messick.[1] Seventeen episodes of Scooby-Doo were produced in 1969. The series theme song was written by David Mook and Ben Raleigh, and performed by Larry Marks and Paul Costello.
Each episode featured Scooby and the four teenaged members of Mystery, Inc, Fred, Shaggy, Daphne and Velma, arriving at a location in the "Mystery Machine", a van painted with psychedelic colours and flower power imagery. Encountering a ghost, monster, or other supernatural creature who is terrorizing the local populace, they decide to investigate. The kids split up to look for clues and suspects while being chased at turns by the monster. Eventually, the kids come to realize the ghost and other paranormal activity is actually an elaborate hoax, and—often with the help of a Rube Goldberg-like trap designed by Fred—they capture the villain and unmask him. Revealed as a flesh and blood crook trying to cover up crimes by using the ghost story and costume, the criminal is arrested and taken to jail, often repeating something nearly identical to "...and I would have gotten away with it, too, if it hadn't been for you meddling kids!"

Scooby Doo has hiden the treasure it is your job to track down some of Scooby's canine friends and with their help find the treasure.

SD1. Astro
Astro the Dog: Astro is the Jetsons' family dog. Prior to being a Jetson his name was Tralfaz and he belonged to the fabulously rich Mr. Gottrockets.
Astro is one of George's best friends (next to his work computer, R.U.D.I.) as well as Elroy's best buddy.
He is able to speak in a rough sounding English resembling dog barks and growls, a manner of speaking which voice actor Don Messick would later reuse for the role of Scooby-Doo.
