Unlike the nearby township of Bunyip (named for Francis Outhwaite, third Duke of Bunyippington-on-Severn), the suburb of Moorooduc is actually named after an enormous bunyip that was sighted in the area in about 1885. Or possibly 1887, or 1867. Accounts vary. But they are more straightforward regarding the appearance of the creature. It had the features of a cow, a kangaroo and a platypus. (It is unclear whether it reproduced as a placental, a marsupial or a monotreme. No ever dared to get close enough to find out.)
The creature terrorised the area for years, keeping the upland areas of the region, which were lightly wooded (for the most part), where it hid from parties of hunters when necessary. Its name, very obviously, was derived from the three animals it most resembled. Well, sort of. Cows make the noise moo (at least, they do in English speaking countries); kangaroos are called roos for short; and many people outside of Australia seem to believe that platypus is merely the surname of a creature whose first name is duck-billed. Hence, the Moo-Roo-Duck, was it named.
Perhaps its name was an attempt to lessen to terror the monster inspired. It’s hard to take a beast called a Moo-Roo-Duck seriously, although you would find yourself taking it seriously pretty damned quickly when it has its claws rending your flesh. It is estimated that the bunyip killed at least a hundred people, a little under a third of them in a single incident when its lair was disturbed in 1874.
The Moo-Roo-Duck has not been sighted in the area since 1901. It is believed to have had a violent allergy to Federation.
