We first catch sight of El Chupacabra when Fred's pen pal Alejo is playing xylophones in a celebration with his young son Jorge, along with their chihuahua Chiquita. They continue to play until Chiquita hears a terrible roar and notices an eerie green light. She runs off and Jorge follows. The boy and his dog run into the monster himself and as El Chupacabra swipes at Jorge, Alejo comes to his rescue and, running into town, cries out "El Chupacabra!" The townspeople, hearing this, run away in fear.
