Finn and Jake awoke safely under the roof of Wolfrick's castle. He had made them a makeshift bed on the floor of his study as the castle only had one proper bed room. He put extra blankets on the floor so Finn and Jake would be comfortable. It wasn't as luxurious as the hotel they stayed at in Aviren, but they made it work. They headed into the castles library in search of Wolfrick. Finn and Jake found him right where they expected. Sitting at a table, nose deep in a book searching for any clues that will reveal the location of the final Legendary beast.

"Any luck yet?" Jake asked Wolfrick.

"Oh, you two are up?" Wolfrick looked up from his book. "Sadly no, but I wont stop until I do!"

"Well, Jake and I will probably head out now. Gotta go show the Ice wraith who's boss!" Finn excitedly punched the air.

"Before you go you two should head down to the kitchen and stock up on food. I'd hate for you two to run out of snacks and have to rummage around the forest for food like animals." Wolfrick instructed them.

"Cool, thanks man. No one wants to eat jank forest grub." Finn said.

Finn and Jake took Wolfrick up on his offer and filled Finn's backpack with all kinds of goodies like, peaches, granola bars, and some packs of trail mix. With snacks in hand they headed off on their new quest. Finn and Jake leaned on the castle gate while they studied the map that Wolfrick had given them. According to the map the Ice wraith's domain was on the complete opposite side of the Overgrown realm. Finn and Jake began the long journey. After a short bit of walking they lucked upon a river that was flowing in the direction they where heading in. Jake, being the awesome shape shiftier that he is, transformed into a sail boat, Finn hopped aboard and the two set sail. Finn kicked back and relaxed for a bit while Jake navigated them down the gently flowing river. After about fifteen minutes of sailing the river lead the two brothers so a sizable lake. Since they couldn't travel by water any longer Jake sailed to the shore. Finn stood far away from Jake on the sandy shore line while Jake shook himself dry. Finn and Jake regrouped and started traveling again. They traveled until noon when they stopped for lunch. Finn sat his tired and aching butt down on a boulder while he ate. Finn ate the peaches they packed while Jake downed the granola bars. Finn took the lead since the path forward was mired with brush. They pushed forth through the thicket of the forest. They where traveling at a snails pace, but it was the best they could do under the conditions present. After a few hours they finally made it out of the thicket and into a mesa. Finn and Jake took a good look around to take in the majesty of it all. The hard red and orange clay that colored the landscape, the beautiful cacti that grew from the barren soil, and all the hills and valleys that surrounded them.

"Woah, this place is mad beautiful." Finn said. "The landscape in this realm is crazy."

"You said it man. Thats one of the only things keepin me sane." Jake admitted.

"What are the other things?" Finn asked.

"Meeting new friends like Wolfrick and Oswald, and of course hangin' with my best bud Finn." Jake said.

"Aw, ya big ham." Finn said as he blushed.

He patted Jake on the head. After their little chat was done the two friends pressed on through the mesa. They continued their travels until nightfall, Finn and Jake where still in the beautiful mesa.

"Man, this mesa is huge! It has to be just as big as the forest." Finn said. "Makes ya wonder why its called the Overgrown realm when such a big part of it is a barren mesa."

"Maybe the people who named this place had never seen the mesa when they named it." Jake said. "Or this mesa might have been part of the forest a long time ago and it just slowly changed over time."

"You so wise Jake." Finn joked.

"I try my best." Jake said deadpan.

"It sucks that we have to spend the night here though. We have no way to make a fire for warmth." Finn sounded concerned.

"don't worry man, you can cuddle up to me for warmth. Just pretend I'm Huntress wizard." Jake said. He transformed into HW's shape and mocked her voice.

"Just cuddle up with me Finny and you'll be fine." Jake giggled.

"Cut it out man." Finn said serious at first, but he quickly lost the facade in favor of giggles.

"I knew you found my HW impression funny." Jake said.

When they finished joking around and playing games with one another Finn and Jake set up camp. Luckily, while they where in Aviren, Jake bought a small, compact tent built for two. Finn pulled it out and Jake helped him set it up and just in time! The sun had just set as they put the finishing touches on the tent. They crawled in the tent to relax for the night. Both Finn and Jake curled up underneath the blankets since the mesa at night time is unbearably cold. After a bit of shivering Finn and Jake finally got warm and fell peacefully asleep. Finn and Jake both had a good nights sleep. Finn dreamed about being back home in Ooo surrounded by his friends. Jake on the other hand dreamed about a never ending sub sandwich with all of his favorite ingredients on it. Jake woke up a half an hour before Finn. After Finn woke up the two ate their breakfast of trail mix and peaches. It wasn't nearly as good as the food they ate in Aviren, but it would have to do. Once their bellies where full they packed up the tent and started traveling once more. Jake took a look at the map that Wolfrick had made for them.

"Hmm, according to this map the Ice wraiths domain begins just on the other side of that mountain over there." Jake said as he pointed to the mountain.

"Cool beans." Finn paused for a moment. "Get it Jake? Cool, cause we're gonna go fight the Ice wraith?"

"Man Finn, that joke stunk worse than rotten eggs." Jake said. Finn giggled.

They slowly walked over to the mountain. Since neither Finn nor Jake really wanted to climb it all the way up the mountain Jake just grabbed a hold of Finn and stretched the two of them to the top of the mountain. They gazed out over the Ice wraith's domain. Light bounced off the fallen snow and ice right back at Finn and Jake, it blinded them temporarily but they got used to it pretty fast. In order to get down the mountain, Jake transformed into a glider. Finn grabbed a hold of him then they set off gliding. While in mid air, Finn looked down to get a scope of the Ice wraiths domain. He saw a group of penguins chilling out beside a small water source.

"Aww, they look just like Gunter." Finn thought to himself.

Finn also saw what appeared to be a group of walruses resting near by. Finn and Jake bobbed and weaved in between the icy peaks of the mountains that peppered the frozen tundra. Jake finally ran out of steam and had to land, luckily they where pretty close to the Ice wraiths lair. Finn checked the map. Said lair was about a ten minute walk away in a ravine. Finn was freezing and he didn't have a sweater, or anything for that matter, to put on for warmth, but Jake, being the loving brother that he is, used his transforming powers to turn himself into a sweater for Finn.

"Woah, thanks man!" Finn sounded happy. "You didn't have to do this though. I'm a big boy, I can handle the cold."

"Nuh uh man, you'd end up in bed with a cold for weeks. And my sorry butt would be stuck taking care of you." Jake said. "You'd be all like 'Oh Jake, I'm so sick. Will you kiss my forehead and tell me I wont die?'"

"I do NOT sound like that Jake." Finn fired back at his brother for mocking him.

"I hate to break it to you man, but you totally do." Jake said with a giggle.

"Whatever man." Finn shrugged him off.

When they regained their focus Finn and Jake headed off in search of the ravine that housed the Ice wraiths lair. After a lot of searching and a bit of luck they found it. Finn edged closer to the ravine in the hopes of sneaking a peek at the Ice wraith to maybe get a small advantage over her, but sadly, Finn couldn't see a thing.

"Aww yoga balls." Finn cursed. "Too bad. I guess we'll just have to go in blind."

"Alright, but watch out for ghastly ghost's and spooky specters." Jake warned.

"Don't worry Jake, careful is my middle name." Finn assured Jake.

"That's a bold faced lie." Jake responded.

Finn didn't answer. Instead he began scouting for a route to safely get down since Jake was preoccupied with keeping him warm. Finn found a way down. He had to be extra careful not to fall to his doom as the way down was coated in ice. After carefully inching his way down Finn finally made it to the bottom of the ravine. Finn and Jake took a good look around. Off in the distance they spotted what appeared to be some sort of fortress made of Ice. Finn drew his sword in preparation for the fight.

"Finn, whatever you do just be careful in there. I won't really be able to help you." Jake warned as he was preoccupied with keeping Finn warm.

"Don't worry man, I will." Finn assured.

Finn crept ever so slowly towards the underground Ice fortress. Once he made it to the wall of said fortress he began making his way around it in search of an entrance. Once Finn found an entrance he took a peek inside. The Ice wraith was inside sitting on her Icy throne. She was a light blue ghost like figure with some sort of veil covering most of her face. The inside of the Ice fortress was beautiful. It had very intricate, very detailed patterned carved into the walls. The flooring looked just like a fancy carpet, but it was just carved Ice just like the walls. There where roman style pillars also made of Ice leading up to the Ice wraiths throne helping to support the ceiling.

"Why have you come here child?" A soft voice called out to Finn.

"Dang it, how did she she me?" Finn wondered to himself.

Finn emerged from hiding and stared directly at the Ice wraith.

"I've come here to kick your frosty butt in battle!" Finn told her.

"Why? What's the point? Don't you understand, fighting is pointless." The Ice wraith said is a somber, depressed tone.

"Sorry, but I really need your treasure. I don't wanna hurt you, but my brother and I really need to get back home." Finn explained their predicament.

"I see." The Ice wraith said as she got up from her throne and approached Finn. "Then just slay me and get it over with. I'm so sick and tired of warriors coming down here to try and slay me only for me to have to off them instead. I've dealt with this for thousands of years. This miserable cycle never ends. Why can't I just live out my eternal life alone like I want?"

She began to cry. Finn put his sword back in its scabbard and walked over to her. Finn put his arms around her in an attempt to comfort her. It made her feel better ever so slightly.

"I can't hurt you if you don't fight back. I'm not some sort donk face." Finn said. "Is their any way you could just give us your treasure?"

"I can't give it to you, 'cause cosmic rules and all that junk. Although I can trade it to you." The Ice wraith explained.

"Oh, ok cool. So... Whatcha wanna trade for?" Finn asked.

"It has to have great meaning to me personally." The Ice wraith said. "And what I want more than anything in the world is to be left alone. Finn, would you bury my palace so nobody can ever find it or me again?"

"If that's what you truly want I'd be happy to." Finn said.

"Oh thank you so much. You have NO idea how long I've waited for this day." She gave Finn a hug. Jake got one too in the process as he was Finn's sweater.

"Oh and don't worry about the treasure, once your end of the bargain is done I'll teleport my treasure to you using my spooky wraith powers 'cause I'm awesome like that!" The Ice wraith giggled.

"Sounds good to me!" Finn said. "Oh, and one last thing before we go. Do you happen to know the locations of the other Legendary beasts? We've already found the Minotaur and the Moth king."

"Of course I know. What do I look like to you, a dummy?" The Ice wraith joked. "The last beast is some sort of rattle snake. He lives in a mesa type place nearby my domain. Hold on, I'll draw you a map."

She summoned Finn a map made of ice that led to the rattle snakes den using her powers. After that was said and done Finn and the Ice wraith shook hands to seal the deal that they had made moments prior. Finn headed back outside the palace. Since he didn't want to climb all the way back out of the ravine, Finn asked Jake if he could stop being his sweater for a moment and stretched them outta there. Once out Finn and Jake began brainstorming for ideas on how to bury the whole ravine. Unfortunately, Finn and Jake weren't known for being the smartest people in Ooo, that's what they rely on PB for, but sadly they were all on their own this time. After a bit of pondering Finn and Jake finally came to the same conclusion. Jake could just use his powers and grow bigger to bury the ravine.

"Duh, why didn't we think of that sooner?" Finn wondered out loud.

"Probably 'cause we haven't been getting the best sleep. I'm sure we'll be back to normal after a few nights in our own beds." Jake assured Finn

Finn nodded. Jake made himself bigger using his shape-shifting powers. He walked over to a near by mountain and ripped its snowy cap right off. Jake carried it back over to the ravine and plopped it down and trampled on it for a bit so ice and snow would fill every crevice of the ravine. After it was all said and done you couldn't tell a ravine had ever been there. All that was left was a tiny hill of snow and Ice made from the leftover snow cap. With their end of the bargain complete it was the Ice wraiths turn to hold up hers. All of a sudden the treasure teleported right in front of Finn just as the Ice wraith said it would. It was a pendant made from the coldest, un-meltable ice in the whole Overgrown realm. A voice started talking to Finn telepathically. It was the Ice wraith.

"Thank you Finn the human. You've truly made me the happiest ghost in all the land!" She thanked him.

"No problem, and thanks for being so awesome." Finn replied.

And just like that they had secured the 3rd treasure. Finn took a look at the map the Wraith had made him. Just as he suspected the mesa the Legendary rattlesnake calls home was the very one he and Jake had passed through to get to Ice domain. Finn and Jake must have been right on top of his lair without even knowing it earlier in the day or the previous one.

"A rattlesnake, dang. We'll have to make sure to not get bit, or else." Finn worriedly paused.

"Or we'll bite the big one." Jake finished Finns thought for him.

Finn left out an audible gulp before answering.

"Yep, or we'll bite the big one."

Finn had a long standing fear of death in regards to him or his loved ones. Coupled with his abandonment issues that stem from his deadbeat dad Martin, so the though of Jake dying really messed Finn up for a quite some time while they traveled. After a tiring and bone chilling journey back through the Ice domain Finn and Jake made it back to the mesa. Jake stopped being Finn's sweater as he wouldn't need the warmth any more, but before heading into the mesa they had one last thing to do. The map that the Ice wraith had given them wouldn't last a second in the mesa since it was made of Ice, so Jake transformed his left arm into the map.

"You're powers are so handy Jake. I wish I had cool powers." Finn admitted.

"You might get cool powers some day. What if you get bitten by a radioactive mouse. You could become mouse man, the super hero with mouse powers." Jake excitedly said.

"That sounds uber lame Jake." Finn said.

"Yeah, I know." Jake admitted. "What even are mouse powers?"

Both Finn and Jake giggled. With all of their business in the Ice domain complete Finn and Jake headed outside the domain that was protected by the wraiths ice magic and into the scorching hot mesa. Jake lead the way as he had the map. According to said map the Legendary rattlesnakes lair was smack dab in the middle of the mesa located at the base of a big hill. They traveled over several hills and valleys, through a sea of cacti, and even came across a small oasis. Finn and Jake took a break at the oasis since they'd been traveling for hours. Finn's shirt was ringing wet with sweat from traveling in the heat, so he took a running start and dove in to the oasis to get cooled off. He left his shirt of so it would get nice and clean. Jake decided to join his brother in the aquatic fun. Jake cannon balled his way into the water. The two brothers splashed and played about in the water all afternoon and evening. It was a much needed moment of rest and relaxation for the both of them. When the sun was starting to set Finn and Jake got out of the water and sat on the sandy beach to dry off. After getting nice and dry Jake set up the tent for the night. Once set up Finn and Jake crawled inside and got a good nights rest. Once both he and Jake had awoken the next morning Finn deconstructed the tent and put it back into its compact carrying case, and just like that they where back on their way. The dynamic duo traveled even deeper into the harsh and foreboding environment until they saw something ominous in the distance. It was an arena of sorts. The walls where made of super sized cacti. There was a tiny entrance on the side that was facing them. Jake examined his map hand.

"You better get ready brother, 'cause according to my trusty hand that s the lair of the rattlesnake." Jake said with a nervous tone in his voice.

"Ready to fight Jake?" Finn asked.

"Ready to fight." Jake assured Finn.

They headed over to the entrance. Finn peeked inside and their he was. Coiled up in the center of the arena sat the Legendary rattlesnake. Without hesitation Finn and Jake heading in eager to get the fight over with.

"My name's Finn, and this is my friend Jake, and we came to." Finn was interrupted by the giant Legendary rattlesnake.

He lunged at Finn and Jake narrowly missing them. Finn and Jake where caught off guard, but they quickly got a grasp on the situation and sprang into action.

"Man, this guy isn't one for introductions is he?" Jake quipped.

Finn ran towards the rattlesnake. Using his trusty steel leaf sword he took a wild jab at the snakes back end. The blade stuck the snake causing very little damage to it overall. The King rattlesnake took a moment to recompose himself before launching another attack. This time his target was Jake. The King rattlesnake grabbed Jake using his tail and started to crush him. Jake yelled out to Finn for help.

"Get me outta here man!" He yelled as he was turning blue from lack of oxygen.

Finn rushed over to help his brother. He slashed and stabbed the beast in his stomach near where Jake was stuck in the hopes of freeing him. The rattlesnake dropped Jake in a moment of panic following being attacked. After regaining his composure and catching his breath, Jake sprang into action and aided his brother in the fight. Using his stretching powers, Jake extended and enlarged his arms in order to grab the large foe around its neck. Jake was careful to grab it in such a way that it couldn't bite him.

"FINN, HURRY UP AND FINISH IT BEFORE IT BREAKS FREE AND BITES ME!" Jake yelled.

Finn, answering his cries, Jumped onto Jake's giant arm and ran up it like a ramp to get onto the mighty beast. Finn raised raised his sword and plunged it through the neck of the giant legendary rattlesnake. It poofed into a pile of dust as the other legendary beast had leaving Finn to fall straight to the ground. Jake wasn't able to catch him in time. Finn fell to the ground and landed square on his butt. Jake rushed over to check on his brother.

"Oh my glob, are you ok bro? You fell from pretty high up." Jake asked.

"Yeah, I'm alright. Just a little bruised and sore is all." Finn assured Jake as he stood to his feet.

"Glad you're ok." Jake patted Finn on the back.

Finn and Jake walked over to the pile of dust and started sifting through it in search of the rattlesnake's treasure. It took them a minute or to but Jake lucked upon the treasure. It was a golden snakes fang.

"Check it out Finn. The last treasure we need to get home." Jake showed off the tooth.

"Woah man, I can't believe we can finally head back to Ooo. I hope our friends aren't too worried about us." Finn said.

Jake handed Finn the tooth to keep safe. Finn put it in his backpack. They exited the rattlesnake's lair and started to make their way back to Wolfrick's castle. The two brothers couldn't wait to get back home.
