After the events of Portal 2, GLaDOS takes up a new hobby. Testing ponies.
Pinkie Pie breaks the Fourth Wall, bringing them to this universe where ponies are tested at Celestial Science. Will they survive testing and make it to the cake? Oh, and Chell is here too!
I am not as good at Portal, as I am at Minecraft, so let's see where this goes.
P.S. You need to have played Portal 1 and 2 or you will be incredibly confuzzled!

Based off of My Little GLaDOS.
Sequel to My Little Portal 2 - Celestial Science. GLaDOS once swore she would never open the folder named 'Project Equestria', but desperate times called for desperate measures. GLaDOS and Wheatly are now ponies with the CMC, and have to live in Ponyville without Aperture Science. What could go wrong?

Celestia wakes up in human form and at an insane asylum where similarities between the world she is in now and the world of Equestria cause her to wonder if Equestria even exists or if she simply made it up to escape her human life. Does she try to hold on to her memories of her Canterlot life or does she let them go and accept them as nothing more than stories? Who is she going to trust? Who is she anyway?

This is only the beginning...

Being the Princess of Equestria is busy work. Luna would know. She raises the sun and moon everyday, looks over the dreams of her beloved subjects, and, well, runs Equestria. Now, in addition to all that, she must find herself a protégé, before her sister's banishment ends!

But, that isn't the problem. The problem, is that three particular fillies stand out for the role!

Who will she choose? Can these three fillies become friends? Who will become Equestria's future savior!?

I guess you'll have to read to find out~!

If that's not bad enough, the Grim Reaper is forcing her to bargain for her life! And what will she do when that bargain takes a somewhat more...personal turn?

You are a changeling lost in the Everfree forest a couple of weeks after the failed invasion attempt at the royal wedding. You're not the brightest changeling out there and you tend to be really clumsy. You only have two goals in your mind right now, one is to get out of this blasted forest, and when you do get out, try not to get captured. Your whole kind is wanted by the royal guard after all.

Queen Chrysalis has only one grub that has survived into fillyhood; her daughter, the physically lame and mentally impaired Crown Princess Pupa. Chrysalis has never been what many would call the 'maternal type', even towards Pupa, whose adoration of her mother has no bounds. Preferring to swamp herself in the dire affairs of state, Chrysalis lets her crippled daughter be raised by her affectionate nanny.

But one day, as the Changeling Kingdom's problems reach boiling point, the Queen's already short temper erupts and she must deal with the heartbreaking consequences...
