Can’t get rid of this one, so I thought I’d give it to the aether:
Pinkie Pie and the Brain.
Pinkie Pie finds an ancient cryo-storage tube in some old ruins underneath the Everfree Forest. Naturally, she pushes the big, red button that no-one should touch and releases the most machiavellian megalomaniac mouse ever known to mankind - Brain.
Mayhem, of course, ensues.
Send me the results, I’d love to see how it turns out.
