One day my cousin was having a party. My two cousins and I stepped outside along with other family members. We started to jump on the trampoline.
Suddenly, my cousin spotted something next to the house. My two cousins and I went to investigate. I was the only one who couldn't see anything. She said that it could be a Duende -- or what appeared to be an elf-like creature. They threw rocks and other objects at it. Then it ran behind an abandoned rabbit cage. One of my cousins said that it bent down to pick up a rock. My cousin's pit bull didn't stop barking during this.
Eventually, the Duende hid and we could no longer pester it because we were scared it may come back to haunt us. We ignored the dog's barks afterward. That was one of the creepiest moments of my life!
