"Well, as I live and breathe, 'course I don't because I'm DEAD, 'tis th' Queen of the Vampires, 'erself." The face, which turned out to be attached to a tattered black coat encasing a ragged shirt and black pants which held a rail-thin body came around the end table, hands raised, "'Ad I knew you was comin', I'da baked a cake – which I can't because the ovens broken, and the burners only work when they feel like it, which isn't often!"
"Attack!" screamed Finn, pulling out his sword as he ran towards the demon whose face had suddenly sprouted fangs and golden eyes. Jake joined him in his brother's run around the table.
The now appalling-faced demon laughed, dodged, and easily flipped the two brothers one after the other so that they landed in the darkness among piles of junk with loud "Ooooofs!"
Which were followed by three, maybe four bodies struggling around in the darkness, knocking things over.
Along with a lot of pummeling and yelling.
That was when Marceline held the blue lamp over them, so that Finn and Jake realized right away that there were only two bodies in the struggle and that Finn had Jake's butt in a hammerlock, with Jake eating Finn's hat.
The demon they'd come out to eliminate was standing beside her, smoking, hands deep in the pockets of his ragged duster, smirking.
"Yo," said Marceline, "You guys are sooooo lame."
Then she broke the blue lamp over the demon's head.
