Author's Note: This story is done in collaboration with ilikekorn, so half of the credit goes to him. It is in continuation of my previous stories. In case you don't want to read my other four stories, here's what you need to know:

Finn is physically an eighteen year old vampire. He and Marceline are 'together.' (They won't get formally married, for some reason. I guess that's too main-stream for them.)

They had a son, a half human, and half vampire hybrid, named Benjamin. He was inspired by ilikekorn as well. Also, Jake and Lady Rainicorn had a litter of rainicorn puppies. The only one who can speak, Jaime, is Benjamin's best friend.

Benjamin has been to the gender-bent universe of Aaa, which is where he met Violet, Fionna and Marshall Lee's daughter. The main cast soon joined him.

I also have two OC's, Ann and Marie, who have played a role in my previous stories. Ann is a multicolored, humanoid candy girl. Marie is a werewolf girl with a wild mane of brown hair. They originally helped Princess Bubblegum and Marceline bond, but they are also notorious thieves.

You should also know for this chapter that the reason Benjamin can go into the sunlight is because Princess Bubblegum created a special sunblock for him, Finn, and Marceline.

This story takes place ten years after my previous one, so Benjamin is about fifteen years old. With no further ado, enjoy the story. This first chapter is from me.

"Why don't you girls just give up?!"

"NEVER!"

Benjamin groaned. "Come on, Jaime, they're getting away!"

Jaime panted in response. They both surged forward, gliding over the grassy fields that surrounded the Candy Kingdom. Their target today was a pair of young, female fiends, a certain candy girl named Ann and a werewolf currently in human form named Marie.

They finally caught up with the girls. Jaime wrapped his long body around Ann while Benjamin tackled Marie to the ground. Ann grunted and struggled, but Jaime just tightened his hold. "Marie, do something!"

Marie turned herself over so that she faced Benjamin. Her expression contorted into canine features. Her eyes flashed blue, her jaw appeared to unhinge, and she released a terrible roar.

Benjamin didn't even blink. He leaned closer to her. His eyes glowed red as he hissed, his fangs glinting in the sunlight.

Marie's face returned to normal. She whimpered, knowing full well that he had beaten her.

He gave her a smug grin. "That's what I thought you'd say."

Benjamin pulled two long pieces of course rope from his backpack. He and Jaime promptly bound Ann and Marie and began dragging the back to the Candy Castle.

Marie began gnawing unsuccessfully on the rope. Ann sighed. "Take it easy, Fluffy. There's no way that you can chew through that when you're not in wolf form."

Jaime looked questioningly back at his captive. "Yeah…do you guys know why we were given orders to capture you? Aunt Bonnie was apparently too busy with royal duties to explain."

Benjamin nodded. "I know, seriously. I mean, I know that you guys are thieves and all, but I thought that Auntie liked you."

Ann tossed her head, attempting to get a stray hair out of her face. "Well, perhaps we took it a little too far this time."

Jaime stared at her, interested. "What did you steal? Her royal tiara?"

Marie snickered. "We stole her diary and sold it to the local Candy Kingdom newspaper."

Benjamin's eyes widened. "You didn't."

Ann shrugged. "What? We needed the cash, and it's not like we stole something expensive."

Marie did another dirty little laugh. "You wouldn't believe some of the junk your Aunt has done. Ordering the genocide of the licorice people, conducting mutation experiments on 'royal guests,' sleeping over with Marceline to practice-"

"There you guys are." Princess Bubblegum stood at the entrance of the Candy Castle. "Please, right this way." She led them in through the front door and down a flight of stairs to the dungeon.

"Hey, how long have my mom and dad been gone?" Jaime asked.

"Oh, they haven't been gone for too long. I only sent them to take down that lava man about half an hour ago."

"Don't worry buddy, with my parents there to help them, they'll be fine."

Benjamin and Jaime tossed the ladies into a cell rather unceremoniously.

Ann whimpered. "Ah, take it easy! I'm fragile."

Marie growled. "Don't we get a trial or something?"

"No. Now, tell us where it all is."

"Where all of what is?" Marie snarled stubbornly.

"Everything that you've stolen in the past. Where are you hiding all of it?"

"Like we'd tell you."

"Very well then. We'll just have to use other means of getting the information we need." Princess Bubblegum looked to Benjamin and Jaime. She snapped her fingers. "Boys, take them upstairs to my bathroom."

They nodded and dragged the girls along. They squirmed and hollered, but it was no use. When they arrived, the Princess filled the tub with the water on its hottest setting. The girls were dumped into the boiling water.

Ann started sweating. "Ah, I'm melting! MELTING!"

Marie howled. "I'M BEING COOKED ALIVE! OH, WHAT A WORLD! WHAT A-Mm." She paused to dip her tongue into the water. "Wow, you taste better than I remembered Ann."

Ann gave the group a dark look. "Fine, we'll talk."

Princess Bubblegum nodded. "That's what I thought you would say."

The tub was drained while Ann listed off the location of various stolen items. "OK, Marceline's laptop is in a tree in the Dark Scary Forest. Marie kind of ate your grandmother's throw pillow, so, ah, sorry about that. Our inter-dimensional transporter is hidden in one of the caves nearby. Finn the Human's boxers are-"

Benjamin interrupted them. "Wait, what did you say?"

Ann smiled slightly. "Yeah, Marie kind of has the hots for your daddy."

Marie blushed. "Oh please, have you seen the way his hair flows in the wind? So. Friggin. Sexy."

"No, before that."

"The inter-dimensional transporter?"

"Yeah. That sounds familiar."

"It should."

"What do you mean?"

Ann raised an eyebrow. "You don't remember?" He shook his head. "Why, you used it to go to the other dimension when you were just a little guy. It must have been…how long ago, Marie?"

Marie bit her lip in thought. "I'd say about ten years ago. Man, now I feel really old."

Ann looked cross. "We are not old. Besides, we don't age physically."

Benjamin put a hand on his forehead. "It's starting to come back to me."

"Yeah, you even got a sweet little girlfriend while you were there." Marie wolf-whistled.

His eyes lit up in realization. "Violet." He turned to Jaime. "Dude, we've got to find that machine."

Jaime grinned and elbowed him. "Oh, I'm sure we do, bro. We've kept your girlfriend waiting long enough, am I right?"

Benjamin scoffed. "Whatever, you totally want to hook up with that cat horse girl."

Jaime blushed. "She was a monochromicorn kitten. And yes, she was totally smoking."

"I'll come with you," Princess Bubblegum volunteered. "I'd like to see where this machine is located so I can ask my guards to pick it up."

They started out the door. Ann squeaked, "Wait, you can't just leave us here like this!"

The Princess turned around and grinned mischievously. "Oh, don't worry, I'll ask the guards to pick you up. In the meantime, if you get hungry, Marie, you can take a bite out of Ann."

Ann looked nervously at Marie, who teasingly licked her lips. "Marie, that's not funny!"

They found the cave with relative ease. Coincidentally, they also found some familiar faces at the entrance.

"Woo, that was mathematical!" Finn, whose clothes were still partially on fire, fist bumped a smoking Jake. The lava man was crying and crawling pitifully away, lighting trees ablaze as he went.

Marceline wiped sweat from her forehead. "Hey guys. What's up?"

Lady Rainicorn spoke in Korean to Jaime, who said something back to her with an excited smile.

Benjamin grinned. "Ladies and dudes, who's ready for an adventure?"
