Imagine hiding from police dressed up as sheep, after escaping from a prison

How often would you have heard of stories of people taking on animal disguises to escape from police ? Not very often, right ? These are mostly part of comics or fiction, but normally you would consider that the physical structure of humans is very different from those of animals, and to consider that a human being could wear an animal outfit and hide from people seems to be a difficult concept to accept. Yet, you have these convicts escaping from a high security prison by wearing outfits in the shape of sheep (which are very different physically from humans) and managing to escape from the police who were looking for them (link to article):

Maximiliano Pereyra and Ariel Diaz stole the sheep hides from a ranch after fleeing from an Argentinian maximum security prison a week ago, The Sun has reported.
The duo managed to evade 300 policemen on their trail by disguising themselves as sheep. Locals have seen them running through farmland at night.
"They were wearing grey clothes but had full sheepskins, including the sheep's heads, over their heads and back," a farmworker was quoted as saying.
