Jake was sitting at home when the phone rang. He picked it up.
"Finn!" Princess Bubblegum's voice came out desperately.
"Sorry, Princess, he's not here," Jake explained to Princess Bubblegum. "He went out with Water Princess."
"Jake," the static voice came out. "Get Finn now. Hurry over, plea-"
The sound of a large crash could be heard in the background.
"Uh oh. That's not good."
Finn was sitting down with Water Princess at a small pond.
"This is really relaxing," Finn said to Water Princess.
"Finn!" Jake exclaimed, running up to his brother. "Princess Bubblegum is in trouble!"
When they arrived, they noticed the Candy Kingdom was melting.
'What happened?' Finn thought.
Then, they noticed it. A giant fire breathing beast. Upon its back, was Scorcher, both of them torching the kingdom down.
Finn and Jake quickly went into action, with Jake blowing out the fires, and Finn attacking the beast. Finn ran onto the monsters neck and stabbed it with his sword. It howled in rage, and shook Finn off.
Jake grew giant and started to blow out the fires. Finn held off Scorcher. They fight on top of the monster, Finn swinging his sword at Scorcher, while the monster was held off by Jake. The citizens ran screaming, while the city was getting destroyed.
Princess Bubblegum was in her castle, which, at the moment, was barricaded. She quickly reached for the phone and dialed, calling the Ice King.
The Ice King showed up in no time. Meanwhile, Jake was scorched, and Finn was burned and bruised. Water Princess helped to put out the many fires. The Ice King showed up and used his ice powers to put out fires and help Finn. The Gumball Guardians helped Jake fend off the monster.
"So, it's you, is it?" Ice King asked. Scorcher didn't respond. Finn distracted Scorcher while the Ice King blew a blizzard, freezing Scorcher. One of the Gumball Guardians lifted the frozen Scorcher, chucking him into the distance.
Jake and the other Gumball Guardian put a stop to the monster, with the Gumball Guardian using its lasers to hurt the monster. It crashed through the wall, and ran off. Meanwhile Water Princess put out the fires.
"Hey, are you okay?" Finn asked Princess Bubblegum, concerned.
"What? Oh yes, Finn, thank you."
They all returned home for the day, exhausted, wondering why an assassin would attempt to burn down an entire kingdom.
"Well, at least it can't get any worse," Finn said, though he had no idea how wrong he was.
At night, Finn sat up in bed and stared at the wall, when suddenly, the house was engulfed in flames. Pieces of wood fell from the ceiling. Thin white smoke was all around the room. No, not smoke. Steam.
"Oh no!"
A fiery figure emerged from the flames.
"Having fun, Finn?"
The Cosmic Owl flew by, squawking. Finn screamed as he woke up.
Finn thought the figure in his dream looked familiar, but he couldn't place it. He didn't want to think about the steam. He had a feeling of what it was.
The smell of breakfast brought him back to reality. He went downstairs to eat some eggs and play some games. He decided that he wouldn't bring up his dreams with Jake, but had a feeling Jake would ask if something was up anyway.
He was playing some fantasy adventure game using BMO, when it hit him. The Keeper. Was this a sign? He thought about it as he continued through the level.
He had just remembered that he had heard some laughter, crazy laughter that he had sworn he heard before. Memories from the dungeon that Joshua had built flooded his mind. There was a demon with one crystal eye that had laughed like that.
He began to get worried. After all, the Cosmic Owl meant something, right?
He and Jake were playing a game of Card Wars, when the door opened. Princess Bubblegum, looking very concerned, ran in.
"Finn, Jake, come outside."
They went outside and immediately noticed that the sky was grey. Princess Bubblegum handed Jake a telescope.
"Look."
Jake looked at the sky and saw a meteor, but when he looked through the telescope, he saw what looked like a small nuclear bomb, black with green.
"What is that thing?" He asked.
"Remember the Lich?" she questioned. They nodded. "Well, he came from a bomb similar to that, along with radioactive material that infected the inhabitants of Ooo."
They remembered the stories Marceline told them. The people, humans, who once lived in the Land of Ooo, had been mutated by the ooze. Nothing could be helped then, but they had a chance this time, to prepare. Finn had a feeling that it had to with his nightmare.
Finn went to see Water Princess, while Jake went with Princess Bubblegum as an emergency royal meeting was called.
As Finn ran toward the Water Kingdom, he tripped. When he looked up, he saw the Fire Kingdom, but there was no fire, only smoke and steam. Three image flashed in his mind. The first was Marceline, the second was Jake, and the last image was of the Ice King.
Finn was being to get worried. What did these dreams - and visions - mean? Perhaps in time they would be answered, as the small bomb was headed for them. The end of the world only drew near, or so they assumed. He had informed Jake of his dreams, or rather, who was in them: The Keeper, as well as the fact that the Cosmic Owl was there. Jake was to relay this information to Princess Bubblegum.
In the depths of a cave system, a Cave Dweller came up to The Keeper.
"Is it ready?" He asked.
"Not yet," The Keeper answered him. He raised his fist, with the underside up. He opened his fingers to reveal a small bee-like creature.
"I only need his DNA. Then, my ultimate weapon will be complete."
"Well, sir, just last night," the Cave Dweller told him, "we obtained these."
He handed The Keeper the strands of hair, one black, another yellow, and the last white.
"Excellent," The Keeper said. "You've obtained DNA from Jake the Dog, Marceline the Vampire Queen, and Simon Petrikov, the Ice King."
When Jake got to castle, the Ice King, and several other royal monarchs as well we're there. They were discussing the bomb headed their way. Jake, remembering the events that occured after Finn's wish to Prismo (resulting in an alternate reality), suggested that Ice King freeze the bomb to prevent its detonation.
Finn reached the Water Kingdom. Right before he entered the castle, he felt a stinging sensation on his neck.
"Ouch!" He looked around, but nothing was there.
"Hmm."
