[I have tried to make this as good as PB could be.]
Princess Bubblegum goes into a secret chamber and goes to a door.
Door: Password?
PB: Never trust CB.
And then goes to another door.
Door: Password?
PB sighs.
PB: Sweety buns 2000.
PB squeezed the doors cheeks and the door opened then she walks up to a safe.
Safe Door: Password?
PB: Glob seriously! Its I'm not jelly 1234.
Safe Door: Password granted.
The door opens and PB grabs her amulet.
PB: Finally ultimate power!
PB evil laughs and coughs.
She goes back up the chamber steps to the chamber exit door.
Door: Password?
PB: Shut up!
The door cries and opens.
She goes to her tower and puts her amulet on then brings out her crown and says a mystic spell.
PB: Uruto Sutkt Famdo!
Her amulet and her crown merged into a mask.
PB: Yes now I am all mighty now no one will say anything about me that evolves...
Finn and Jake come into the room and start beating up PB.
PB: Ow! Owch! Stop!
PB's voice changed then Ice King appeared.
Ice King: Okay okay stop! How did you guys find me?
Finn: We followed you into the chamber and heard the things you said and Peebs wouldn't say that junk.
They hear screaming coming from a closet and they open it.
PB: Thank you that old oaf locked me up.
Ice King: Who are you calling old you are 3...
PB kicks him in the shin then Ice King falls.
Ice King: Ow! For a princess you kick hard.
PB: Hmph!
Ice Kung was captured and locked up and was in questioning PB walks in.
PB: How did you find out about my amulet old fool?
Ice King: You think that I wouldn't find out... that amulet has powerful ancient power!
PB: I figured you would be around to know.
Ice King: I know more than you think I'm not as crazy as you think.
PB: Next question. What were you planning on doing with the amulet?
Ice King: Unlock its power!
PB: Okay I've heard enough take him out...
