The adventures of Marshall & Fionna Story 1: From Aaa to Ooo and back again.
Her gleaming eyes, Marshall thought. Fionna yawned. "When are we going to get there, Marsh?" Fionna opened her eyes. "No peeking, it's a surprise." Marshall said. Fionna shut her eyes. "When are we going to get there?" Fionna asked in a disgraced voice. "Soon" Marshall replied. They drifted down in front of the tree house. Their toes swiftly touched the ground and slowly felt to tickle their feet. "Umm... Marshall," "Were at the tree house" Fionna complained. "Yea, I know." Marshall explained. "So, we started where we ended." Fionna said.
"There is a world called Ooo. It's just like Aaa, but the genders are switched. It's a few years back so, since your 15 there is a boy just like you that is about 12. My younger sister, Marceline, or Marcy is 990 years old. I'm ten years older than her." Marshall said. "So, what does have anything to do with anything?" Fionna asked. "Well, I want to visit my sister, and," Marshall gulped quickly "I was wondering if you wanted to go with me." Marshall replied. "Sure." Fionna replied. "Whew. I was worried you were going to say no" Marshall said. "How do we get to this Ooo place anyway?" Fionna asked.
"First of all, my sister and I are two of the few immortals that can go from Aaa to Ooo or Ooo to Aaa. All we have to use is this skeleton key." Marshall said. "What? No secret portal, or fancy rhyme or anything?" Fionna asked. "Oh, there is a portal; you just need a key to it." Marshall explained. "Obviously somebody can steal it." Fionna mentioned. "Well... Umm... no they can't" Marshall Lied. "O really?" Fionna said. "I keep my key in a secret and safe place." Marshall said.
