Chupacabra

The Chupacabra is a mythical creature that is released in Undead Nightmare. Killing one will earn the player the Chupathingy (A reference to the popular machinima Red versus Blue) achievement/trophy, and complete the final requirement for the Undead Hunter challenge. 'Chupacabra' in spanish means goat-sucker.

The Chupacabra can be found in the fields North West of Torquemada. When zoomed out on the game map, the area will have a picture of three horses. The creature can also be found South East of Perdido, or south of Casa Madrugada, or North of Chuparosa near the river. When the Chupacabra is nearby, a blue marker will appear, along with the message: "A mythical creature has appeared." The Chupacabra looks much like a Hyena and it's incredibly fast, but can be killed by the traditional shot to the head.

NOTE: the Chupacabra can only be encountered once the player has reached the Undead Hunter Rank 5 Challenge. Also, killing the Chupacabra is the only way to unlock the Unicorn.
