One of the most common reports from a sighting is about the face. Eye-witnesses talk about the eerie sensation of a human being looking right back at them.
These are people who know the difference between a human being and an ape. Their island is also home to the Sumatran Orangutan. Many dismiss Orang Pendek as being a mistaken glimpse of that great ape instead.
But Littlefoot isn't red. It's not even vaguely orange. Accounts habitually talk about short brown fur, turning grey as they get older. Except for the head.
The Orang Pendek has a mane of long, flowing hair there, just like a human being.
But they are strong, so very strong compared to us. They might be short, but their muscular prowess is more akin to that of a chimpanzee. The tough rattan vines can be snapped in two in their hands. They can uproot small trees.
Much of this power derives from their broad shoulders and long arms. While slender in all its aspects, it is extremely sturdy and robust.
It is also bipedal, with the small, dainty feet that have given Orang Pendek the moniker of Littlefoot. They are said to be the size of a human child. Footprint casts and photographs have revealed the requisite five toes. But the big toe is divergent, like the thumb on a human hand.
But most of all, people return to that face. In 1923, Dutch farmstead settler Mr Van Heerwarden seemed to speak for all, when he said, "There was nothing repulsive or ugly about its face, nor was it at all apelike."
And yes, he had seen an orangutan, gibbon and sun bear. He knew the difference.
