"I've spent years trying to find a cure to my brother's curse." Princess Bubblegum said as she finished her story. "Unfortunately all he kept his research hidden in his personal lab. Even I don't know where it is."
"Maybe he left a clue." Finn said hopefully.
"Well, there is this amulet." PB said as she pulled out the amulet. It was a sphere of black stone rimmed in silver with a gold chain.
"Let me see that." Jake said as he grabbed the amulet. Suddenly, silver writing began to form on the amulet. "What the glob!" Princess Bubblegum quickly took the amulet back.
"Scientia Sit Potentia. This is Latin!" PB exclaimed.
"What's Latin?" Finn asked.
"Latin is an old language, Finn. My brother taught me how to read some of it. I think it means knowledge is power." Princess Bubblegum explained. As soon as she translated the phrase the amulet began to glow, a hologram of Roy from before the transformation appeared.
"Bonnie, if you're listening to this then my experiment failed. If this is true then there is only one way to save me. Hidden near Marceline's house is my secret lab, this amulet will guide you there. Inside is all my research on curing the curse, as well as the means to destroy me if all else fails. The safety of the Candy Kingdom must come before all else, and if I become too big a threat then you must kill me." The hologram of Roy said sadly. "I'm sorry it had to come to this. Good luck." The hologram then disappeared.
"We have to get to Marceline's cave before the Frost Prince can do too much damage!" PB exclaimed.
"Hold on!" Jake said as he picked up Finn and PB and set them on his back as he grew into a giant. Jake then started walking towards Marceline's, covering miles with each step.
One ride across Ooo later
"We're here." Finn said as he hoped off Jake's back onto the cave floor.
"But where's the lab?" Jake asked as he shrunk back to his normal size.
"What's the amulet say PB?" Finn asked as Princess Bubblegum pulled out the amulet. Suddenly a compass arrow appeared on the stone pointing at the cave wall.
"Over here." PB said as she walked over to the wall. When she got close, the wall a section slide away to reveal the lab.
"This place is amazing!" Finn exclaimed as he walked into the lab. The lab contained several half finished inventions all surrounding what appeared to be a nuclear reactor.
"I found the research." Princess Bubblegum said holding up a stack of papers. Suddenly Marceline walked into the lab.
"What's going on guys?" Marceline asked wondering why they were in her cave.
"We accidentally released the Frost Prince and now we got to find a cure for the curse before he destroys all of Ooo!" Finn explained.
"What?! Do you realize what you've done! I was barely able to stop Roy the first time!" Marceline shouted.
"Don't worry Marceline, we've got the formula for the cure. Right PB?" Jake said unconcerned.
"I just have to find out what went wrong the first time and then I can make the cure." Princess Bubblegum said without looking up from the paperwork.
"You don't understand we don't have time to wait for the cure." Marceline exclaimed. "When I stopped Roy the first time he was working on something big. Something that could have changed the face of Ooo forever."
"What was it Marceline?" Finn asked.
"A nuclear bomb!" Marceline said ominously.
Sorry for the delay. Hopefully I will update again next week.
