(Fionna's POV)

She ran towards the candy castle. Her feet pounded against the ground. For once, she was desperate. Not like before when the Ice Queen had Marshall, Fionna had been scared but not like this. Wind hit her face and blew her bangs back and tugged against her bunny hat. Her thoughts buzzed around her head and no matter what she did, she couldn't push them aside.

Fionna ran past little candy people, ignoring the urge to just bite into one of them. Her stomach growled. Her heart raced as she did as well. She came to the castle to see Cake, her fur bristled. It made her sister look twice as big.

"Fionna! Girl, where have you been?!" The cat yelled as she approached. Fionna stopped and explained everything as quickly as she could. Cake's eyes widened and she kicked down the castle door. Fionna already knew where they were. She ran through the halls with Cake at her side.

Sweat poured down her face when she finally reached the lab. She kicked the door down to see FP in PG's body alone. The window was broken, and the prince was hugging his knees. Cake's fur bristled as she leapt to attack him, but Fionna held her back.

"Don't! Remember what I said about attacking the body?" Fionna scolded.

"Right, right," Cake sighed, allowing her fur to flatten. The human girl glared at FP (in PG's body)

"Where is he?" She called to the prince. He whipped his head up, but didn't snap back.

"Right here," He squeaked.

"Yeah right-" But she noticed that the crown jewel color had changed to black.

"I mean it! Ask me anything that only Marshall would know," He said, scrambling to his feet.

"Alright… What did you use to get us out of the Ice Queen's castle?"

"A match and a bottle of olive oil. You said that you like to use it for slipping monsters, but it worked too. I had dropped the match into the bottle and threw it at the door with ice blocking it. It had melted it before going out, and I had carried you to a field where you leaned on a tree." Fionna gasped.

"I-Is he right?" Cake quietly asked. Fionna nodded and ran over to Marshall in PG's body. She embraced him, and he awkwardly wrapped his pink arms around her. Fionna then pulled back.

"Then… what happened to FP?" She said in a tiny voice. She already knew the answer.

"He traded bodies with me. So know PG is in FP's body, I am in PG's body, and FP is in my body." She bit her lip.

"Girl, when I get my paws on that FP I will rip him to pieces," Cake muttered to herself.

"Wait… Marshall, how did he switch bodies with you?"

"I didn't see it that clearly, but I think it had something to do with the jewels. Like the one in PG's crown and FP's head." Fionna sighed and just kept in his arms. He twirled one of her bunny hat ears around his finger and sighed.

"If only there was some way to switch us back-"

"Ice Queen!"

"What?! Where?!" Marshall yelped, whipping his head around. Fionna shook her head with a giggle. He glared at her with fake anger. She smiled.

"No, that isn't what I meant. The Ice Queen is against the Fire Prince, so maybe she will help us-"

"Help us?!" Cake shouted. Fionna sighed and crossed her arms.

"Hear me out. She loves jewels, she hates the Flame Prince, and wants PG. Those are three reasons why she may help us."

"Call me crazy, but that may actually work. Ice Queen, here we come."
