Scooby-Dum, a white Merle Great Dane with a red hat, red collar and buck teeth is Scooby-Doo's slow-witted cousin. Dum lives with Ma and Pa Skillet, in the Okefenokee swamp of southern Georgia. Whenever Doo and Dum greet each other, Scooby-Doo yells, "Scooby-Dum!" and Scooby-Dum says, "Scooby, Doobie, Doo!" They then do a special handshake involving two high fives. Whenever he heard the word "clue", he would invariably pull out a magnifying glass and, intoning the opening four notes of "Beethoven's Fifth Symphony", chant, "Dum, dum, dum, DUM!" even after a mystery is solved.
