Across the 2nd Fanon Dimension

Chapter One: Breaking the Fourth Wall
The 2nd dimension Phineas and Ferb were bored. The Heinz Doofenshmirtz in their dimension had long ago been defeated by their first dimension counterparts, and now they had nothing to do. The solution? The Internet.

The surfed the web for quite a while, searched DeviantArt and found a terribly-written Phineas and Ferb fan fiction called The Hearer. After that, they became bored again and decided to Google their own names.

One of the first things that popped up was something called the Phineas and Ferb Fanon. That seemed interesting enough, so they clicked on it.

They had no idea how different the site was from the one in the first dimension.
