Answer:
The girls wake up to the sound of goats. Outside the barn, they see a boy leading a small herd of goats toward them.
The boy introduces himself as Chencho and gives the girls water. Odilia has a bad feeling about him; she feels uneasy.
Chencho offers to lead the girls to Hacienda Dorada, and Odilia tells him that isn't necessary, but the girls end up seeing him again after they leave the barn and begin traveling together.
Chencho leads the girls to an old house that he sleeps in and tells them about his experience with a chupacabra.
Chencho turns into a chupacabra and attacks Pita. The girls blind him by poking out his eye.
They consider killing him but decide to let him go when they realize that it's Chencho
