Heat Signature (episode)

"Heat Signature" is the twenty-fourth episode of the second season of Adventure Time.

Synopsis
Marceline plays a prank on Finn and Jake by making them believe they're vampires.

Plot
So far the only known details of the plot involve Marceline preforming a "biting ritual" to turn Finn and Jake into vampires. She tells them to close their eyes and to keep them closed or their heads would explode. Rather then bite them, she merely pinches their necks and dabs ketchup on them to simulate a bite wound. When asked how they feel, Finn says he feels the same, and Jake says his neck hurts.

Trivia

 * This episode was originally called "Blood Drive".
 * The title card has Jake spraying red paint on a billboard for Heat Signature in a destroyed urban background, and what he is painting is Lady Rainicorn.﻿ The tagline "Under the ocean no one can hear you die" is printed near the bottom of the billboard.
 * This episode has the same name as a movie Finn and Jake were going to watch in the episode "Video Makers", except it was Heat Signature 3, apparently the third movie in the series.
 * This episode was originally scheduled to air on April 25, 2011. However, due to a last minute programming change, it was moved to Monday, May 9, putting it after the two-part episode: "Mortal Folly" along with "Mortal Recoil". This makes "Heat Signature" the new season finale because of this.Tennically the episode is before Mortal Folly being paired with Video Makers most likely.
 * Marceline's clothes in this episode are re-color's (Orange/red shirt, brown ripped jeans, and dark gray boots.) of the clothes she wore in her very first appearance. There are some minor modifications, such as her ripped pants and shorter boots.
