I've been stuck like this for about a decade, and I'm finally free. But of course, those pony friends of that evil jail keeper aren't happy about that. Why? Don't I deserve a shot at life too? Just because I have to lock up Pinkie Pie in my mind? Hah! She deserves it for doing it to me!

When Pinkie retreats into her own mind due to the depression of thinking her friends abandoned her in 'Party of One', Pinkamena finds herself in control of herself for the first time since the Sonic Rainboom. But her friends aren't too happy about Pinkie Pie being locked away in Pinkamena's place.

Now has a sequel!

Imagine being stuck in the mind of a pony that you can't stand and is the exact opposite of you.
Now imagine having your life torn away from you, and you've just gotten it back; only to face just as many hardships as before.
And then imagine you were just told you technically shouldn't even exist.
That's my life.

This story is a sequel to Caged Inside, but is written in a way that it's not necessary to read it first.
