El Chupacabra

El Chupacabra is a ghoulish monster, created by Professor Frink. El Chupacabra escapes from Frink's laboratories, and ends up at Moe's Tavern.

Creation
El Chupacabra was created by Professor Frink. It wasn't actually the Puerto Rican Chupacabra, but it sucked the blood of a goat like its Puerto Rican counterpart. Frink had a device that could tell if the creature was near. It was attracted to the bar because of Barney's Burp.

Battle and Death
It killed Moe, Wiggum, Bumblebee Man, The Sea Captain, and Jasper. It wounded Barney. When trying to suck the blood of Barney, the alcohol got into its bloodstream, and the El Chupacabra died. Only Homer, Frink, and Barney survived.

Behind the Laughter

 * El Chupacabra is Spanish for "goatsucker". The creature derives its nickname from its supposed habit of attacking livestock (particularly goats) and drinking their blood.
