Netflix’s Stranger Things introduced the world to the Upside Down and it’s monsteriffic denizen, the Demogorgon. Some characters had unfortunate run-ins with the creature, including Barb. After her death, she took on a gruesome appearance that would be a blast to replicate for Halloween. If you’d like to look like Barb, Kiana Jones, a.k.a. Freakmo, has a makeup tutorial with you — complete with a how-to on making the gross slugs.
