La Mancha Negra - IRL Symbiote?

I know, you think you already know everything about The Black Stain or Spot or Smudge or however it's translated, but there's more to this story than a fast talking dude can cram into 4 minutes. Plus, the story gets really entertaining. Not only that, but we involve the testimony of people actually familiar with the situation! Which seems kind of weird that no one else does... is it really that hard to get ahold of Venezuelans? Hold on... let me call my missionary friend in Venezuela to ask.
