I bet atleast one of you has read a book written by Tara K. Harper! I love her books!
In one of the books there is spoken about this animal called a six legged Dnu. This is the way I pictured it to look like, a six legged cross between a sheep and a cow(like those Scottish ones)! Looks cute, ne? If you look at this pic from a distance it will look like the beast has only four legs, and not six.
