Rattlesnakes are venomous snakes often found in the United States of America. A rattlesnake is one possible corporeal form of the Patronus Charm.[1]
They were either Lavender Brown, Fay Dunbar, or their roommate's worst fear, and, when they encountered a Boggart in Defence Against the Dark Arts, it took the form of one.[2]
