Weird ****, when I first watched the video I was like "Jesus H. Christ!", but then I was like "Why didnt they run up and kick it?"
They didn't kick it because it is a Duende! The black ones are spirits of the forest who appear (usually accompanied by a loud, weird whistling sound) whenever young people are (or have been) treating an animal cruelly. The black Duende don't take kindly to that kind of behaviour, and it is wise to fear their wrath.
White ones are okay, but you don;t kick them.

Those kids would no more kick a Duende than an Irishman would kick one of the Little People (who are ironically referred to as the "Good People" because referring to them as anything else might provoke them to anger, and they will seriously **** you up).
Ask a devout (superstitious) Muslim if they would go toe-to-toe with a Jinn. Or ask a Pagan if they would fight the Green Man. Ask a Christian if they would happily tackle a demon. They wouldn't.
Plus, obviously, it's The Sun.
Here's another Duende appearance for you... It's only a little one. They are always little guys (of varying sizes) with spiked hoods on... like a mini-KKK. Some are more convincing than others

And if the Duende don't get you, the witches will:

EDIT: Duende are also moving into North America (except Arizona, obviously) so be afraid!
