Finn and Jake had been planing this adventure for months. Deep in an underground cavern they found an old, monster infested comic book store. It was from before the mushroom war, so Finn and Jake where hoping to score some pre-war nerd goodies.
"Hey Finn, what do you think will be in there?" Asked Jake as they headed to the cavern.
"Some comic books and video games for sure. Maybe some movie posters and action figures if we're lucky." Finn answered with enthusiasm.
"I hope we find some pre-war munchies." Jake said.
"Dude, I think I'd croak if I ate goodies that old." Finn said with a concerned expression on his face.
"Not me man. I have a gut of steel." Jake assured Finn.
"Just don't eat to many, ok? I don't wanna loose my brother." Finn was concerned for Jake's well being.
They arrived at the cave. Finn lit his lantern and they headed inside. They went deep into the cavern until they reached the abandoned comic book store. They snuck up to a broken window of the store. They looked in and saw a dilapidated interior, crawling with monsters. The monsters where a moldy green color, oozing with green slime. They had piercing red eye's and they appeared to work as a unit.
"I dunno Jake. It doesn't look like there's to much in their and it looks super risky. Maybe we should just forget it and head home." Finn suggested.
"Are you kidding? We can only see the main room in their. There's gotta be all kinds of loot in the storage room, and besides, I'm ready to kick some monster booty." Jake was determined to go in.
Finn sighed then said. "I guess you're right. Lets go in.".
They busted into the shop through the window. Finn drew his sword and started to slay the monsters. Hey slashed and stabbed his way threw the hoard, but more and more monsters poured in from the halls. Jake morphed his arm into a mace and helped Finn clear the room. After 8 minutes of battle they cleared the main room of the building. They started to look around the room for loot.
"Aww man, all that's here are old, moldy comic books." Jake disappointingly said.
"Told ya so." Finn smugly replied.
"Patience Finn, the goodies aren't always in plain sight." Jake said.
After they thoroughly searched the main room they began searching the smaller rooms in the hallway. They searched the bathroom and only found Monster goo. They searched what appeared to be the old owners living quarters. In their they found some centuries old cheesey chips, and a VHS tape that was still in workable condition. Jake took the chips and Finn put the VHS in his backpack. They made it to the final room. It was a sizable storage room. It was filled with old inventory that was still in good condition.
"See? What did I tell you?" Jake rubbed it in Finns face.
"I guess I was wrong." Finn admitted.
They sifted through the inventory. Finn found some comic books from the "World savior" series. Jake found something that he had always wanted. A mint condition poster for his favorite movie series "Heat Signature".
"Finn! Hey Finn, look what I found!" Jake ecstatically told Finn.
"What is it bro?" Asked Finn.
Jake showed Finn the poster.
"Woah, neat! That has to be super rare. You where super lucky to find it." Finn told Jake.
"Yeah I know. It must be one of a kind." Jake said as she shape shifted a back pack to put his loot in.
They did one last sweep of the room to make sure they didn't miss anything. Other than an old can of soda, they didn't find anything. They headed out into the main room. They where getting ready to leave when out of the corner of his eye, Finn saw a piece of the wall that was boarded up.
"Wait up Jake." Finn said as he pointed to the place in the wall.
"Good catch Finn." Jake said.
They walked over and investigated it. Their appeared to be something on the other side, but they couldn't tell just what it was. Jake shape shifted his arm into a giant hammer and busted down the boards. Behind the boards was a tiny crawl space. They got on their hands and knee's headed into said crawl space. They made their way through the crawl space. On the other side they found a secret room. It was in perfect shape. It was like time had never touched this room. It was filled with crates.
"Geez. This room gives me the creeps." Jake said.
"I know what you mean man. There's just something off about it." Finn responded.
They took a better look around the room and what they saw shocked them. The walls where lined with battle plans detailing an attack on the Candy Kingdom, the Flame Kingdom and the Ice Kingdom. It quickly became apparent to them that this room wasn't originally part of the building. It had been built much more recently.
"We gotta warn Princess Bubblegum." Said Finn.
Before Jake could respond the two heard a nose coming from the vent. A group of people where heading through the vent.
"We gotta hide!" Jake frantically said.
Finn and Jake quickly opened the lid to a crate and jumped in. Finn made sure he put the lid back on nice and tight. They could see out of a small crack in the wooden crate. They saw four men, humanoid in nature, but where a sickly green color and had some sort of serpentine fins and scales on their head. They where carrying more crates with them. One of the men looked around the room to make sure their where no intruders.
"The coast is clear. Whoever killed our guard demons must be long gone." The man said.
Finn and Jake tensed up after he said that.
"Excellent." Another man said.
"All the stuff is here. We can arrange a meeting with our client to discuss payment." Another man said.
After getting everything in order. The group of four left through the crawl space. Finn and Jake Stayed quiet in the crate for fifteen minutes to make sure they where far away. Once they decided they where long gone, they hopped out of the crate and better inspected it's contents. The crate they hid in contained a bunch of armor. The second crate they inspected had a bunch of weapon's like swords, spears, and battle axes. The next crate they opened contained a bunch of spare machine parts. The final crate they opened contained a bunch of green glowing rods.
"Woah." Finn said.
"These look pretty dangerous." Jake said.
"We have to take one to show PB." Finn said.
Finn grabbed one of the glowing rods and put it in his backpack. Jake grabbed the war plan poster's off of the wall. They headed back through the crawl space. Once on the other side they crawled on their hands and knee's as to make sure they we not seen if the strange men where still around. They snuck out of the store and into the cave. They made their way up to the surface and bolted towards the Candy Kingdom.
