This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Peluda (French)
The Peluda in Spanish, or La Velue ('The Hairy One') originally in French, is a mythical beast that terrorized the environs of the River Huisne, France, during the Middle Ages. It is called "The Shaggy Beast (The Hairy Beast) of La Ferté-Bernard" in English translation.
The supposed serpent-headed creature had a body covered in long green fur with poison-tipped spines protruding. It caused flood (or shot out fire from its mouth) that destroyed crops, devoured livestock and humans, and struck humans and animals dead with its tail. It was defeated after it tried to prey upon a maiden named l'Agnelle; her fiancé slew it by delivering a sword-strike to the tail, its only weak spot.
