|Not in FusionFall Retro.|
| The following article is about something that appeared after the Birthday Bash update in FusionFall, and so will not appear in FusionFall Retro.|
As such, it solely exists for archiving part of the original game.
Jake is Finn's anthromorphic dog and partner who possesses magical powers allowing him to grow larger, stretch his limbs to extreme lengths, and other similar powers. Jake and Finn grew up under the same parents, Jake's, when Finn was found by Jake's family as a baby.
War Against Fuse
In The Future , Jake was alive. He was stationed in Sector V as a jump pad for heroes to hop onto or look at the statues.
In the past, Jake is seen in the Ice King's Fortress, as well as in Sector V, positioned near the statues of Hero's Square. In both locations, he is an NPC and a jump pad.
Chasing the Ice King
Jake, Finn, and Princess Bubblegum left Ooo to track down and stop the Ice King, who managed to flee Ooo and enter the FusionFall world to kidnap princesses. After arriving, Finn requests to see the hero in Orchid Bay to help him, Jake, and Princess Bubblegum save princesses who have been abducted by Ice King. Once the hero arrives he/she tricks Ice King into believing thet he/she is the television repair man. Ice King lets him/her into his palace and the hero finds the gang in his Basement. There he/she is told of the gangs plan to rescue the kidnapped princesses. Once the hero is filled in about the plan, Bubblegum sends him/her to save the first princess: Candy Wife. Ice King somehow kidnapped her after Birthday Bash.
Helping Candy Wife
After getting the mission from Princess Bubblegum, The hero invades the Ice King's dungeon to set her free. There Jake helps the hero get out of a pit. Once out of the pit, the hero clears the path of Glacial Golems and heads towards Candy Wife's cage.
After the hero completes the task for Princess Bubblegum, Finn request his/her assistance for the next part of their plan. He seems to have overheard The Ice King called her Princess Princess, so he guesses that means she's even more of a princess than Bubblegum. Princess Bubblegum seems to be a bit jealous for some reason, thus meaning that he can't rescue Princess. The hero then sets out to rescue her from a prison inside a giant ice cavern through a dungeon door. Inside, Finn tells the hero to hop down off the platform he/she is standing on (via NanoCom), take out some of the Glacial Golems below, and make his/her's way to Jake, who has said that he'll meet the hero on the other side of the cavern to help him/her out. After the hero talks to Jake, he waits for the hero to hop on his back so he/she can jump onto the quickly moving floating ice platforms. When the hero reaches the prison platform, he/she must defeat a giant Ice Titan to clear the way. Once the Ice Titan is defeated, the hero rescues Princess. Once freed, Princess shows ungratefulness towards the heroes actions.
Stationing in Sector VJake appected to be a jump pad in Sector V (Hero's Square), so heroes could see the new statues of Ben, Chowder, Finn, Flapjack, and Rex.

–FusionFalls' website description of the Twelve secret snails
Magic Snails from the Land of Ooo have inched their way into FusionFall. Legend has it that each snail will transport a person to a magical glade and bestow upon you a truly algebraic prize: exclusive Adventure Time gear! It would seem they hitched a ride with Finn, Jake and Princess Bubblegum when they set out for the FusionFall world.
Jake seems to have given DexLabs a sample of one of his personal items, for Nano creation.
His Nano can be seen at Mt. Neverest along with Mordecai Nano, Rath Nano, Rigby Nano (which was released this July), Waybig Nano, and Ultimate Big Chill Nano. He, along with Rigby, Mordecai, and Rath are the only Nanos to be sent from Mt. Neverest into battle.
Solving a Mystery
|“||If you do love adventure, which we've already established is pretty likely, then you know what time it is. That's right: Adventure Time! Finn's good buddy, Jake, needs your help over in the dungeons beneath the Ice King's Palace. It seems that something disturbing is going on with Finn who seems to have been sneaking around behind Jake's back and now the Enchiridion has gone missing!||”|
