One day you wake up to a...wierd world with lots of colors, the sky is blue, and wacky creatures all walking around like normal

One pale beautiful woman in a sun hat looks at you

"A human? I thought Finn was the last one."

She starts to smirk as she plays her bass

"You look loss. How about this? I drink your blood and eat your heart!"

She laughs at your panic

"I'm just kidding. I'm Marceline the Vampire Queen. This is the candy kingdom...probably the sweetest place in all of Ooo"
