Well, my personal experience was not in seeing the creature but a tale as told to me and my fishing kakis deep in the Endau/Rompin Nature Reserve in Malaysia. It has not been gazetted yet as a Nature Reserve when I was fishing there as a young kid.
It was in the '80's and we were at the upper reaches of the Endau River and our 2nd trip. After a tiring day of nothing but casting and catching fishes up and down the uppermost reahes near the waterfalls we return back to our campsite. As usual after dinner, we took out our rods baited them and cast them into the river and mount the rods on the rod stands, sat down behind the rods waiting for a bite.
The guide, who has a motorised sampan was the penghulu (headman) of the last Orang Asli village, called Kampung Peta along the river. We were all sitting down bear the rods and enjoying our coffee and not making too much noise so as not to frighten away the fishes. Speaking softly to each other, the guide told us of this sighting he and his people experienced. That was how I knew about this creature, and at that time, mind you there was no TV, not much in the way of communication in their village except for the occasional trips to the nearest town for supplies and outsiders which were few and far between as the village was pretty remote. Also during that time any news or stories about Bigfoot were uncommon even in modern Singapore.
The tale he told was about several rare sightings he and a few of his people had had of the creature. He described the creature as I mentioned before and the large footprints left behind as the creature was very shy and runs away from humans. The hairs left behind on some branches were long and dark coloured and the place it was last seen has a very bad stench. Sometimes they did not see the creature but knew it was there because of the smell.
It was only after year 2000 when there was some excitement about this creature and it's footprints and the news about expeditions to search for it. There has not been any success as far as I know.
