Not much is known about the Chupacabra due to the fact that it was only mentioned. It is mentioned when Gordon tells Sam and Dean he's more of a go-it-alone type of a guy to which Dean responds with "Come on, man, I've been itching for a hunt" to which Gordon responds with "Sorry. But hey, I hear there's a chupacabra two states over. You go ahead and knock yourselves out."
It is mentioned again after Sam and Dean investigate the death of a victim of ghost sickness and Sam asks Dean what could scare someone to death to which Dean responds with "What can't? Ghosts, vampires, chupacabra? It could be a hundred things".
In a flashback, a younger Sam mentions one.
During a phone conversation between Arthur Ketch and Sam and Dean, Arthur tells them that their mother is busy hunting a Chupacabra in Texas.
