I''ll carry you home(Marshall lee and fionna fanfic)

The secret

I arrived at gumball castle. There were no guards? I went invisible and went to the royal guard room.All the weapons were still there were had they gone? I felt a presence when I walked past the laboratory. I went inside just to check it. It was normal. But still it was just not normal here... I took a quick look around to make sure everything looked normal. glass cups, geen stuff, bones, blue cloth. I stared at the blue cloth this kinda looked like this belongs to fionna. I looked around to find it source. I heard a banging strait ahead.There was just wall. I touched it and felt cool surface.What the heck was going on!?could this be what I was looking for. I broke it to see a horrible shock it was fionna...
