A/N: I don't own Adventure Time or anything from The Nightmare Before Christmas. I do own Russell, Brenda, and Brad though! Oh, and From this point on, the P.O.V. alternates between Alexis's and Brenda's.

Brenda's P.O.V.

"BRENDA!" PB shouted about two weeks later, flinging the door to Fionna, Cake, and my room open.

I screamed and rolled out of bed. I got to my feet and exclaimed, "You know, I was sleeping peacefully!"

"Oh, I'm very sorry," PB said.

"Yeah, whatever," I muttered. I said, "So, what's so important that you had to wake me up?"

"I found the man who wrote the book you found!" PB told me.

"You found his grave?" I asked.

"No! He's still alive! He's an immortal skeleton and ragdoll man," PB told me, "He looks twenty three, but is really more than a thousand years old."

"Wow. Really?" I asked, "Older than Marceline?"

"Yup. He lives in the Hinterlands in the haunted forest," PB told me, "He's the king of, some old holiday, Halloween."

I grabbed my sword and put it in its holster. I said, "I'll go alone. I can handle myself."

PB nodded at me and I ran out of my room and then out of the tree house.

After a few miles of flying a few feet off the ground, I finally got to the haunted forest. There were seven trees. One with a four leaf clover, one with a turkey, one with a red square with white stars on it, a heart, a green tree with decorations on it, a painted egg, and a pumpkin with an evil looking smile on its face.

"Glob dang it! PB never told me what door to go through! Maybe I can guess," I said. I thought hard for a few minutes. I said, "Halloween sounds spooky and scary. The pumpkin looks spooky and scary. Wild guess, here I come."

I walked towards the pumpkin door and turned the handle, the nose of the pumpkin. It creaked open, and a cool air pulled me in the tree. I screamed as I fell.

When I finally hit the ground, I felt a lot of dead leaves. I got to my feet and started to walk towards some lights, which I guess was the town. I passed a very scary and thin scarecrow. There was a sign above the scarecrow's head. 'Halloween Town,' it said.

"Don't let it scare you Brenda. It's just a scarecrow," I told myself, walking towards town.

When I got to town, it looked like it was deserted. "Hello?" I called.

"Hello," I heard someone say.

I turned and saw the scarecrow. I screamed and drew my sword. "No, no! I won't hurt you miss!" The scarecrow told me. The scarecrow turned to a burning stick, picked it up, and swallowed it. Within moments, the scarecrow's clothes and head caught fire. He jumped into the fountain and a figure emerged from the water. "That, miss, is how you get the scarecrow costume off easily," He told me. He smiled at me and stepped out of the fountain.

I said, "Sir, I'm looking for the King of Halloween."

"Well, do you know his first name? I could help," He told me.

"Oh. My friend never told me his first name. Just that he was the king of Halloween," I told the tall man.

"Well, I could help you," He told me, "But first, I must know your name."

"Brenda the human girl. One of the last humans in existence, sir," I said.

"Well, my name's Russell. Russell Skellington," He told me, "Follow me."

I followed him up to a mansion and he opened the door. He let me sit on a strange couch and he sat across from me. "Nice to meet you. Princess," He told me.

"What? How did you know I'm a princess?" I asked Russell.

"You said you were one of the last humans. I put two and two together Brenda. Plus, your pink friend stopped by earlier in the week and told me," Russell told me.

I looked around the room. It had dark colors and the color orange. "So," I said after ten minutes of silence, "You wrote Famous People Before The Mushroom War?"

"Yes and no. I did write it, but the title I gave it was Famous People," He told me, getting to his feet and getting a book off a shelf. He sat back down in the seat across from me.

He threw it and I caught it before it hit the floor. "Famous People," I said, "This is my book?"

"No, it's one of my copies. It has Alexis and Alex in it," Russell told me.

"Who?" I asked.

"A and A," Russell told me, "Look in the book."

I opened the book and saw the picture of the girl with the red, white, blue, and brown hair, grassy green eyes, and pretty red dress with a dark blue ribbon around her waist, long red gloves covering her arms, with red half inch heels. She was still wearing a red mask to hide her face. I looked at her name. Alexis. I turned the page.

The man just as pretty as Alexis was on the next page. He was wearing a black tux with a green tie. Both his arms were covered by his black tux sleeves, and he was wearing black fancy gloves. He had the same grassy green eyes and brown hair as in my book. Alex.

"Alexis was my best friend for a long time. Then my girlfriend," Russell said, smiling. His smile faded when he said, "I never saw her again after I got back to Earth."

"Earth?" I asked, confused.

"What Ooo was called before the great mushroom war," Russell said bitterly, "It killed all non-immortals. Most people on earth. The humans, a lot of the animals, and it was so close to killing Alex. He froze though. Some blue guy froze him in ice."

Ice King. That idiot. "So, what happened to Alex?" I asked.

"I'm not sure. He was frozen in ice somewhere. That's all I can remember," Russell told me. He lifted some of his hair and showed me a big bump on his head. "This bump was almost a thousand years ago," Russell told me, talking his hand away from the bump, "I don't think it's going to go away for a few more months."

He laughed and I said, "So, you're the king?"

"Yup. Russell Waylon Skellington The Pumpkin King," Russell said, smiling.

"Then it's nice to meet you," I said. I heard his stomach growl.

"Sorry. I haven't eaten in a long time. My food supply ran out about a month ago," Russell told me.

"Then come back to the surface with me!" I exclaimed, "We have enough food for everyone!"

Russell looked up and said, "That would be wonderful. I wouldn't want to trouble anyone though."

"Oh, it's no trouble at all! Really!" I exclaimed, "Everyone would be glad to meet you!"

Russell smiled wide and said, "I would love to go Brenda." We got to our feet and Russell said, "You can keep that copy, I have tons."

I put the book in my backpack and he started to collect things around the room and put them in a silver bag with purple spots. He said, "I got this bag from Alexis. It's like her PAK, the thing that keeps her kind alive, but it has straps, so it doesn't connect with my spine."

I raised an eyebrow. "Alexis is an irken. She needs a PAK to live and breathe. An irken is a green skinned, bald, alien with black antenna. Long and curly for girls, short and strait for boys. The girls also have eyelashes," Russell told me as he collected more things into his backpack.

Finally, he grabbed one of his Famous People books and shoved it in the bag. "Alright. I'm ready to go," Russell told me. We walked out of his mansion and I followed him back to the trees with doors on them.

Russell said, "These doors haven't been used in almost a thousand years. Halloween," He pointed to the pumpkin shaped door, "The best holiday. It let all the spooks and monsters free for a night. That was all they needed before the Mushroom War. When that stupid war came, the mortal monsters re-died. The vampires, werewolves, Barrel, and my younger siblings. My parents, on the other hand, just disappeared. I don't know where they went to."

"What happened to all the other holidays?" I asked.

"No one celebrates their holidays anymore, so they don't come out. Plus, I think most of Santa's elves are dead," Russell said, muttering the last part to himself.

Two hours later, we were almost at the Candy Kingdom's castle. When Peppermint Maid and Peppermint Butler opened the doors, we walked in PB and PG's lab and I exclaimed, "Bubblegum! I found him!"

Bubblegum, of course, was holding a beaker, which she dropped and broke. "Brenda, you are so lucky that wasn't acid!" Bubblegum shouted at me. She noticed Russell. "Who's he?"

"This is Russell, the pumpkin king," I said, "The one that wrote the book I found in your library."

"Really? Do you have another copy?" She asked Russell. Russell pulled one of the books out of his bag and handed it to Bubblegum. She flipped through it, looking at all the different people. She stopped at the page before Alex, but after Alexis.

"Who's she?" Bubblegum asked.

Russell took the book and said, "This is Shadow. She was Alex's girlfriend for sometime. She disappeared sometime before the Great Mushroom War. She was the daughter of Slender Man. He killed many children, and had no face. Even so, Shadow got her facial features from her mother and was very kind."

"Okay," Bubblegum muttered.

A/N: Nicky: I hope you liked! Shadow, Alex, Alexis, and Russell all belong to me, just in case you were wondering.
