It's become a concerning issue that Finn's red pajamas have been 'mysteriously' turned white, so he and Jake are on the case.

10:00 AM, Finn wakes up to discover that his once red footie pajamas are now white.

"WHAT THE STANK?!"

Jake hears the shout from their room and turns the stove off, climbing up the ladder to see what's wrong. "Finn? What's—oh my glob." Upon seeing the disgruntled blonde in all white, face scarlet, Jake recalls the time that a lady Sasquatch mistook him as her baby and laughs. "What happened, dude?" he asks, stretching over and tugging on Finn's white pajamas. "Your pj's are all...white."

"That's what I'm trying to figure out! It had to have been Marcy or Marshall.."

11:00 AM, Finn and Jake investigate the scene of the crime for any traces of aforementioned vampires.

Jake sniffs around, crawling on his hands and knees in order to get accurate results while Finn looks around with his magnifying glass. So far, they've found nothing. Until...

"Hoorah! A clue!" Finn cries, holding up a piece of red fabric.

Jake glances at it. "But who does it belong to?" He meanders over and sniffs the fabric, his nose size increasing to sharpen that particular sense. "Smells like...strawberries."

Finn's eyes grow as wide as saucers. "Quickly, to the...downstairs!"

"You mean the second floor?"

"No time for corrections!" Finn exclaims, grabbing Jake's arm and climbing downstairs.

Once they reach the second floor, Finn's assumptions are correct. The bowl of strawberries that was sitting on the table only two minutes ago is missing!

"I'm onto you, Abadeer!" Finn bellows, climbing out the window and onto the roof before Jake or BMO, who had just walked into the room, can say anything.

"Was that Finn? Jake, what is going on?" BMO asks, running up to the window and looking skyward.

"We're about to solve the mystery of the White Pajamas!" Jake answers before stretching onto roof.

BMO raises an eyebrow, but shakes it off and climbs down to the first floor. From there, the lovable robot heads to the pond and exclaims, "Hello, Football!" He pulls a loaf of bread from behind his back and rips a piece off, tossing it into the water. "I brought you lunch!"

Football's face lights up. "Yay, lunch! Thank you so much!" she exclaims, reaching for the bread. Before she can grab it, though, one of the ducks eats it. "Nooo!" she cries, weeping.

"Carlos! That was for Football!" BMO scolds, ripping another piece of bread from the loaf.

11:03 AM, Finn and Jake climb onto the roof and find the perpetrator.

"I knew it!" Finn exclaims, pointing an accusing finger at the vampire under the umbrella, who is currently sucking the red from a strawberry.

Jake raises his eyebrows in slight surprise. "Oh. Hey."

Marshall Lee Abadeer smirks and flicks a drained strawberry at Jake. "Go away, doggy. This is between villain and victim," he orders, morphing his hand into a giant bat hand and grabbing Jake's head with it.

Jake holds back a scream and stretches away, leaving the human and vampire king alone.

"Why'd ya do it?" Finn asks in his best Bostonian accent, glaring Marshall down.

The vampire lets out a low chuckle and floats over to the human. "You're so cute that I could suck the red from your cheeks~."

"But my cheeks aren't red—"

"I wanted to lure you into my little trap, and it appears to have worked. Now let's fly!" Marshall exclaims, wrapping his arms around Finn's torso and flying away, causing the boy to blush from surprise and sudden contact.

11:07 AM, Marshall flies Finn to an unknown place.

"Those were my only pajamas, y'know," Finn states, watching the scenery below them fly by.

Marshall shrugs. "You can have my old ones. They don't fit anymore."

Finn blushes. Marshall's pajamas? He can't wear his crush's pajamas!

12:00 PM, Marshall lands on a cliff.

"So, why did you want to trick me?" Finn asks, hugging his knees to his chest and watching the clouds.

Marshall suddenly scoots up behind Finn and wraps his arms and legs around him. "Because I like you," he whispers into his ear.

12:01 PM, Marshall's confession causes Finn to turn around and kiss the vampire king right on the lips, much to Marshall's surprise and pleasure.
