A/N: Stupid little one-shot that the plot bunnies were bugging me with. I just wondered what would happen if Teto was a test subject at Aperture Laboratories and this was born! Disclaimer: I don't own Portal, Portal 2, or UTAU/ Vocaloid. Story time!
GLaDOS was bored. There was no other word for it. Her test subjects had long since left and GLaDOS was left alone to come up with science to do and bake cakes no one ate. Just then, GLaDOS had an idea. Why not experiment on artificial humans? They wouldn't question her or run away! GLaDOS quickly made a teleporter and hit the button. Within moments, a pink drill haired android was in the first testing room. "Welcome beta number 12,345. I'm GLaDOS. Go pick up your portal gun." GLaDOS commanded. The pink girl did so and walked to the middle of the room. She curiously shot one portal onto the ceiling, and another onto the floor. "Hey! What are you doing? Solve the puzzle/test!" GLaDOS shouted. The pink haired girl looked confused for a minute and then shrugged and jumped into the portal on the floor. "WHEEEEEEEEE! TETOTETOTETOTETO! TETO ENJOYS THIIIIIIIIIS!" the girl (whose name seemed to be Teto) sang as she fell faster and faster through the two portals. GLaDOS sighed. It was going to be a LOOOONG day.
A/N: And, we're done. I'm sorry if GLaDOS is OOC, I really haven't played that much of Portal 2, I've just watched a friend play parts of it, trying to explain it to me. I still don't understand the cake thing...
