"Ha ha ha!" Ice Queen laughed evilly. "Finally! I have come up with a plan to make Marshall lee mine! With this potion, I will look and talk exactly like Fionna, and Marshall lee will fall right in my trap! And only he will see me as Fionna!"

Ice Queen drank the potion and fainted. It wouldn't be long until she awoke to take charge in her evil plan.

At the tree house, Fionna and Cake we dead bored.

"So do you wanna go track down some bad guys?" Cake asked.

Fionna gave a long sigh. "I guess. There's nothing better to do."

"Great let's go." Cake said while getting up.

An hour later Ice Queen woke up and made her way to the tree house. She let herself in.

"Hmm, now where is their phone?" Ice Queen asked herself. "Aha! There it us."

Ice Queen called Marshall lee and invited him over.

"Um, sure Fionna." Marshall lee said with a hint of confusion.

A few minutes past and Marshall lee knocked at the door.

"So, you wanted to see me, Fionna?"Marshall lee asked.

"Yes, I need to tell you something." Ice Queen said.

The potion had worked! Marshall lee actually thought Ice Queen was Fionna!

"I like you and I want to go out with you." Ice Queen said.

Marshall lee was shocked. Never in a million years did he think Fionna liked him.

"Fionna, I feel the same way." Marshall lee said.

Their lips her inches apart and Ice Queen closed the gap between them.

Fionna and Cake soon got tired and headed home.

"Now that was fun!" Fionna exclaimed.

"You got that right, sugar." Cake said.

They opened the door and what they saw horrified both of them. Fionna dropped her sword and Cake fainted.

"Ah!" Fionna screamed.

Marshall lee and Ice Queen quickly parted.

"Fionna?" Marshall lee asked now very, very, very confused.

"Ah! Marshall lee what are you doing kissing Ice Queen!" Fionna yelled.

"Ice Queen! But she...and she...but..." Marshall lee couldn't find that words to explain all of this.

Marshall lee turned to Ice Queen, but she was gone.

"Fionna, listen to me-" Marshall lee tried to explain, but was cut off.

"No, I think it would be best if you just go." Fionna said.

Marshall lee could see how hurt Fionna was just by looking at her. Marshall lee left the tree house o find Ice Queen and make her explain all of this.

"Ugh, how could I've been so stupid!" Fionna yelled at herself.

Cake woke up after a few minutes.

"Oh my! I had the worst dream! You and I walked in on Marshall lee making out with Ice Queen." Cake said with disgust.

"It wasn't a dream, Cake." Fionna said.

Once again Cake fainted.
