Who is Scooby-Doo? He's a lovable Great Dane who solves mysteries with his friends in the Mystery Inc. gang. Scooby-Doo and his pals, like Shaggy, Fred, Velma, and Daphne, travel around in their groovy Mystery Machine van, encountering ghosts, monsters, and all sorts of spooky stuff. They always manage to crack the case and unmask the villain in the end. Scooby-Doo is known for his goofy personality, his love for food (especially Scooby Snacks), and his iconic catchphrase, "Scooby-Dooby-Doo!" Zoinks!
