Adventure Time Comic Issue #23

Finn and Jake have been taken over by the Gum that's swarming the Candy Kingdom and Princess Bubblegum believes that "she" won't stop until "she" has covered the entire world. Marceline wonders hows Princess Bubblegum knows the gum's genderand as the banging gets louder she convinces the princess to tell her what she knows about it.

Princess Bubblegum relays the story (with improv narration from Marceline) of how she woke of one morning several years earlier and wanted to have a child to succeed her as ruler. Not having the time or patience to raise a child of her own so she decided to inject her DNA into other Candy People, which failed completely. After removing her DNA from the Candy People, she decided it was best to go alone and used her scientific skill to create a child from gum and the experiment was succeeding until Princess Bubblegum gave "her" a Candy Heart.

The story is interrupted as the brainwashed Finn and Jake are able to break through the door. Marceline is able to transform into a monster and subdue the two into test tubes while Princess Bubblegum re-welds the door shut. Bubblegum is able x-ray the two and she discovers that the gum has worked it way into their brains, which is a problem as Princess Bublegum knows nothing about brain surgery.

At that point, the Gum finally breaks through the door and Finn and Jake break ot of the test tubes. Marceline turns into a monster, grabs Princess Bubblegum and bursts through the castle walls. They find that the Gum has spread all across the land, except for one place. Castle Lemongrab, with theEarl of Lemongrab waiting for them.
