Animated short

The Adventure Time with Finn and Jake animated short was originally created as part of Frederator Studios' Random Cartoons on Nickelodeon.

Synopsis
In the original short, Finn is actually named Pen. Pen is sleeping under a tree in a sleeping bag when he wakes up and asks Jake what he's doing. He tells him he is meditating to connect his mind to the internet. Then he shows him a dance he downloaded. Just then, Princess Bubblegum's Lady Rainicorn flies by crying. Jake turns huge and the two follow Rainicorn. Pen tells her a joke to cheer her up, but it turns into a failure, for she just kept on crying. They chase her into the Ice Kingdom where Ice King starts shooting at them with frozen lightning bolts. Pen says that he is an oxymoron and Jake shrinks. Pen sees that Ice King trapped Princess Bubblegum. After Pen puts on a turtle-neck sweater, he asks Jake if he wants his booties and gives it to him. They yell, "Adventure Time!" and Pen and Jake jump and slide into the ice and they surf on Penguins. They land into the ice, but they spotted an Iceclops. After they throw snowballs at it, they then spot a Snow Golem and they throw snowballs at it as well. Then they see a Fire Elemental who asks for directions to the sun. Pen gives the directions, then throws a snowball at the Elemental. This makes him upset so he asks how old they are. Pen says that he's twelve and Jake is twenty eight. They then hear an evil laugh and they look up to see Ice King. Jake stretches his legs to boost Pen up to Ice King. Pen tells him to stop it and Ice King tells him to stop meddling and that Pen and his dog can't harm him. Pen says that he's not his dog but his friend and then kicks Ice King into his house and cave, where there was a drum set and a pair of underwear. They kung fu fight as Jake flirts with Rainicorn. Pen asks Ice King why he's always stealing ladies. Ice Kings replies that he's going to make one marry him. Pen says that the king's idea is stupid, and Ice King says Pen's hat is stupid. Pen gets mad and kicks him in the face as he screams his hat is awesome. Then he realizes that Jake is not helping him, so he looks out to see him talking to the Rainicorn. Ice King uses his frozen lightning bolts to freeze Pen in a block of ice. Then, his mind gets transported back in time and onto Mars, where he meets Abraham Lincoln. Lincoln tells him that all that matters is that he needs to believe in himself. Pen screams "NEVER!!!" as his mind is transported back to the present and breaks out of the ice block. He sees Ice King fly away with Princess Bubblegum who yells for them to help her. Rainicorn, Pen, and Jake chase after Ice King. Pen jumps and grabs the princess as they land on Rainicorn. Then Jake knocks the crown off of Ice King's head and Ice King falls to the ground. Jake walks away on his out-stretched legs.

Pen and the princess land as Pen tells her that she is free. The princess kisses and thanks Pen. Jake comes and asks what is going on and Pen says nothing. Embarrassed, Pen drags Jake away and says that they have stuff to do. Jake denies it and says that they have nowhere to go. Pen laughs and says that an adventure awaits. Jake says that he doesn't see an adventure going on anywhere and that they should just sit there and talk about their feelings. Pen randomly points at three Ninjas stealing an Old Man's diamonds. He says bye to the princess and the princess bids farewell. Pen and Jake say it's "Adventure Time" again and they run off.
