The term 'Legend Himalayan Beast' refers to the YETI, a mythical creature said to inhabit the Himalayan Mountains. It is also known as the Abominable Snowman and is described as an ape-like creature with white fur. The YETI is believed to be a cryptid, an animal whose existence has been suggested but not proven. Reports of sightings of the YETI have been made since the 19th century, but no physical evidence has been found to prove its existence.
