There was one problem: the artwork was very frightening. After much thought, the phrase 'Scooby-Dooby-Doo' was so fun that they decided to call the show Scooby-Doo, Where Are You? and they made the dog the star of the show.' And with those words Scooby-Doo was created with the other characters supporting him.
The new show was now more comical then mysterious. Don Messick became Scooby with his trademark laugh and scratchy voice, Top-Forty DJ Casey Kasem became Shaggy who was always in a constant state of panic and hunger which also served as Scooby's partner, Frank Welker became blond Freddy, Nicole Jaffe became brainy and bespectacled Velma, and the trouble-prone, sexy Daphne was the voice of Heather North. There were other voices that supported the main crew. One worth mentioning is David Coulier who was the star of America's Funniest People and Full House. The teenage Coulier made a voice tape that told a story and mailed it to Hanna-Barbera on a Friday. The next Monday Hanna-Barbera called Coulier and said "We have work for you on Scooby-Doo." Coulier was only 18 years old!
