You were exploring the abandoned corporation that was Pear Inc. (which was the corporation that made your favorite show) when you fall in a hole in the floor and go unconscious. When you wake up, you find a blue sphere staring over you. You would recognize that sphere anywhere.. that's Balloon Sphere, or as the other characters in the show called them, B.S.!

B.S.: "Uh.. you alright? You did took a long drop..." Balloon Sphere asked in a worried tone for you.
