BOOM! CRASH!

"... Er... Jake? You awake dude?" Finn whispered as he rubbed the sleep from his eyes and slowly looked around for his magical dog companion. He spotted Jake tossing and turning in his bed.

"Ooohh, I am now!" He grumbled. "Why you makin' so much noise? I'm trying to sleep, Finn!"

CRASH!

"Dude," Finn began as he jumped out of his bed to Jake's side. "That's not me..."

Jake perked his floppy ears in fright. "Dude! We gotta check it out." Finn explain as he began slowly making his way to the ladder leading to the lower level of their tree house.

"But duuudde!" Jake wined. "What if it's Marcy trying to scare us again?"

Finn paused at the top of the ladder and gave Jake a serious look, "Then why would investigating be bad? You aren't scared of her still, are you?" He laughed as he continued down the ladder. Once at the bottom, he paused and examined the area through narrowed eyes. 'I wish it were lighter in here!' He thought.

Jake stumbled shakily down behind Finn, "S-scared? I'm not-"

CLANK!

"AHHH!" Jake screamed as he retreated back to their bedroom. Finn simply shook his head and laughed.

"Finn the human!" A deep voice adressed him. "Princess Bubblegum has asked us to retrieve you. She has an important mission for you heros."

Finn's eyes lit up at the sound of another epic mission, "Richious!" He shouted as he ran up the ladder to change and retrieve Jake. "Dude! Dude! It's okay! It was just PB's Gaurds, hah. She wants us to go on an important mission!"

Jake slowly calmed himself and smiled, "Pshhh! I knew that!" Jake lied as he crawled out of his bed and headed downstairs to wait for Finn.

Soon enough, Finn was ready. He headed downstairs and they were off.

(Time Skip~)

"You called PB?" Finn asked.

The princess turned to the young human, "Yes, Finn. I have a very important mission for you..."

Jake narrowed his eyes to slits, "What's the mission about?" He pressed.

Bubblegum nodded with understanding and told the story of the Banana Man's report and her earlier exploration. Finn and Jake listened in awe.

"So now, I'd like you to scope the scene. And if you can... And this /is/ real, please learn as much as you can."

Finn smiled at the princess, "M'kay princess, will do. Come on Jake!"

Jake turn to finn with a well known smile, "What timeis it?" Jake asked.

"ADVENTURE TIME!" Finn replied. And with that, they bolted out the door.

(Time Skip~)

They soon arrived.

Finn paused at the entrance and gazed into the gapin hole in awe. "Duuuddde..."

Jake poked Finn on the shoulder and smiled, "Get on my back homey, I'll stretch us down there." Finn nodded and returned a smile as he climbed onto the magical dog's back. Soon enough, they began to stretch to the bottom of the cave nearest the pool.

"Alright." Finn began as he climbed off Jake. "We have to go into... Wait. This pool, it's from your croak dream!"

Jake remembered his false dream followed by the bizarre events it brought. "Oh my glob!" Jake exclaimed. "You're right!"

Finn clung to Jake, "We go down together..." Jake sighed and plunged into the pool.

They floated for a moment and looked around. Where should they swim? Suddenly they see the all too familiar earth in the distance. Jake quickly swims forward, his mind on reaching the underwater earth. All the while, Finn was losing air faster than Jake.

(Time Skip~)

Jake breaks the surface with a gasp for air and an unconscious Finn. He set Finn down on the stoney cave floor and gave him CPR. "Finn!" He wailed.

Soon enough, Finn came through. He coughed up the cold cave water and looked around. "W-what happened...?"

Jake glomped Finn and snuggled his bro. "You're alive dude! I almost lost you!"

"Dude, I'm fine!" Finn laughed and hugged Jake back. "Now what happened?"

Jake released his grip on Finn and stood up. "We swam through the puddle- Wait a sec here! We're back in the cave! This is bananas Finn!"

"No kidding... Guess we should report back to the princess then." Finn suggested as he hopped onto Jake's back. Jake nodded and quickly stretched to the cave entrance.

The sunlight blinded them as they resurfaced the world. "Agh!" Finn cried as the sunlight hit his eyes. Jake stretched over to a patch of grass and set Finn down, then he furociously blinked his eyes in hopes of adjusting them to the light quicker.

"Baby get back! Rapid dog!" A female voice cried as she pushed her taller companion behind her and assumed attack position.

"Huh?" Finn turned to see a female girl whom strangely looked like his twin. And then notice the angered feline at her feet. "Wait! We aren't bad!" Finn explained. "We're totally heroic!"

Cake let her fur lay slightly flat. "I don't know if I should trust y'all..."

Suddenly the girl kneeled down and began to whisper something in the cat's ear. "Oh-oohhh! I'm sorry for my rude behavior!" She suddenly apologized.

Finn gave a confused glance to Jake and stood up. "I'm Finn, and this is Jake."

The girl stepped forward, "I'm Fionna, and this is Cake..."
