"I know. Okay. I know, Antonio. . . . So needy."
-- Grindelwald before kicking a helpful Chupacabra out the door of a Thestral-drawn carriage (CG)
A blood-sucking creature with both humanoid and reptilian qualities, found in North and South America.
A baby chupacabra named Antonio helped Gellert Grindelwald to escape from Ministry Aurors who had come to fetch him where he was being held prisoner by MACUSA authorities. Antonio bit the finger of an Auror named Spielman, allowing Grindelwald to steal the Thestral-drawn carriage in which they were riding. For his trouble, Antonio was given a pat on the head, then kicked out the door into the Atlantic Ocean along with Spielman.
Commentary
Etymology
Chupacabra or Chupacabras - Spanish for "goat-sucker"; from chupar, "to suck", and cabra, "goat"
The name is attributed to Silverio Pérez, a comedian from Puerto Rico who coined the name on the radio while discussing attacks on local goat herds. Sightings of the creature began in the Caribbean, but the phenomenon quickly spread all South America and even into the American southwest as the name of the vicious beast spread by news coverage and magazine articles. Possible explanations for sighting of the Chupacabra range from hairless dogs or coyotes infested with scabies, to vampire bats which really do suck the blood of farm animals, to some weird hybrid creature that was accidentally released from a government research facility.
