Muggles' Guide to Harry Potter/Magic/Yeti

Overview
The yeti, commonly known as Bigfoot or the Abominable Snowman, is a troll-like carnivore completely covered in pure white hair. Native to Tibet, yetis fear fire.

Extended Description
In Harry Potter and the Chamber of Secrets, Year with the Yeti is one of the several supposed autobiographies of Gilderoy Lockhart that are assigned to Harry's Defence Against the Dark Arts class. Harry is selected by Lockhart to play a "yeti with a head-cold" in a dramatisation of one such story.

Analysis
Whilst being largely regarded as a myth by the scientific community, the yeti remains a common feature of fiction and one of the most famous creatures of cryptozoology. True to this, it is mentioned in Fantastic Beasts and Where to Find Them that an International Task Force is based in the Himalayan mountains so as to prevent reporting of Muggle sightings of the yeti, which are apparently numerous.
