Dr. Horrible's Sing-Along Blog and Penguins of Madagascar Crossovers
A Brand New Day by jackandjill2 reviews
Takes place two years after Billy's final video blog. Dr. Horrible can't stand this world any longer... but, when he finds a way to travel to a different world, will it be any better? Rating subject to change, but it's looking good so far.
