This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Yowie (Australian Aboriginal)
Yowie is one of several names for an Australian folklore entity that is reputed to live in the Outback. The creature has its roots in Aboriginal oral history. In parts of Queensland, they are known as quinkin (or as a type of quinkin), and as joogabinna, in parts of New South Wales they are called Ghindaring, jurrawarra, myngawin, puttikan, doolaga, gulaga and thoolagal.
The yowie is usually described as a Bipedal, hairy, and ape-like mythical creature standing upright at between 2.1 m (6 ft 11 in) and 3.6 m (12 ft). The yowie's feet are described as much larger than a human's, but alleged yowie tracks are inconsistent in shape and toe number, and the descriptions of yowie foot and footprints provided by yowie witnesses are even more varied than those of Bigfoot. The yowie's nose is described as wide and flat.
