The people of Nepal call it "rakshasa" which is Sanskrit for "demon". According to them, stories of its existence date back to the 4th century BC. Yeti means "magical creature".
According to legends, there are three species: the Rimi, the Nyalmot and the Raksi-Bombo. In spite of differences in size, the species
have a general resemblance. The Yeti has reddish hair, smells terrible and it is very strong. It makes an ululating, whistling sound, and is sometimes heard roaring like a lion.
I caught a story on the Discovery Channel one evening involving an Englishman on approach to one of their camps. There was a "squaking warbling" sound that came from behind the men on the trail. The sherpa all got down to their knees and said, deadpan, to their shocked white leader:
"Yeti coming, sahib."
