Lost In Ice (Various x Fem. Reader)

Dad's Dungeon

Another cloud passed over the treehouse, blocking the setting sun only for a moment before it floated by. In the boat, located at the top of the tree, was the hero trio, along with their dearest friend, BMO.

Finn was sat at the edge where a telescope was set up. He let out a yawn while Y/n was on the other end under the umbrella with her head tilted back.

There was a soft smile on her lips as she enjoyed the fading sun glistening on her face. She let out a sigh before the familiar flaps of wings got closer.

Peeking open an eye, Campi flew down in their eagle form and landed on the side of the boat with a small squeak.

They then hopped down and flopped over on Y/n dramatically to also lay back and enjoy the sun.

Jake stood in front of everyone while bending his knees eagerly. "Alright. Whaddaya wanna see next?" He asked.

"A cheetah! A fart!" Finn raised his arm up in the air.

"A cookie! An external hard drive! Ooh, ooh! Change into Finn, but give him my body!" BMO gestured down with a small flap of their arms.

Finn blew a raspberry with a roll of his eyes. "BMO, your ideas are boooooring."

"What?" BMO paused, a faint look of embarrassment on their face. "Your head on my body isn't boring! It's weird!"

They giggled while Y/n picked them up and held them in the air.

"Yeah, just weeeeeeiiirrrddd." She drew out the word with a smile before placing BMO on her stomach to rest.

Jake rubbed his hands while taking a step back. "Alright, I'll try to turn into a cheetah farting."

With a farting sound, Jake started to slowly morph his body into one of a cheetah.

Once he got the shape right, his head and tail started to move around his body like a conveyor belt. He then stopped before his eyes dilated.

"I can't do the spots."

Behind Jake, on the leaves of the Treehouse was a bunch of sparkles making the leaves float up just a little.

"Sparkles on the house?" Finn's eyes lit up with excitement. "LET'S SQUISH 'EM!:

With a leap, Finn and Jake jumped after the sparkles while pushing through the leaves until they disappeared under them.

Y/n sighed loudly before patting robotic BMO's head gently. "Get down safely little bud, looks like an adventure's happening." She said before hopping after the two.

Inside of the leaves was a very well hidden, and secret, attic space. Y/n glanced around while letting out a small 'woah'.

"Oh, snap! Well, plop that cartridge in the slot, playah!" Jake clapped. Both he and Finn were kneeling in front of a teal trunk. Inside were different cartridges and a holo-player.

Finn looked at one before placing it inside the machine. "Yeah! Okay!"

The player hummed to life before a pink hologram appeared. Y/n stood behind the boys and leaned forward with her hands on her knees.

The hologram showed a living room with a fireplace in the center of it. In the back was a giant sword sitting as a centerpiece on the mantle.

Stepping into the frame was a dog. One is similar to Jake. In his arms were two babies, which he held with pride.

"Hello, boys." The dog spoke before coughing.

Finn's eyes widened while Jake's mouth hung open. "Dad!!" They both cried.
