We were thrilled to get a whole miniseries focusing on Marceline, Adventure Time’s resident vampire, a while back. Adventure Time: Stakes is out on DVD today—and to celebrate, here’s an exclusive clip showing the animatics of the story’s scary climax.

Spoilers ahead...

In this scene, Marceline has been cured of vampirism AND she’s killed the super-vamps who came back to life after her vampire essence was released into the world. But now the essence of the most powerful, terrifying vampire of all has become a huge dark cloud, and Marceline feels like it’s all her fault. The creatures getting sucked up into that horrible cloud is even scarier as a series of sketches, for some reason.
