The Alternate Ending

You know how at the end of each episode, Phineas says, "Oh there you are Perry", and the invention disappears? This is my story about that.

One day, a boy named Peter (see Phineas and Ferb movie by AgentP, not made yet) was visiting the boys. They made a bunch of stuff, and the last day, they made the VGSTTYPAIIITG (Video game system that takes your picture and inserts it in the game). This is my ending.

Har D Har Toy Factory
The boys went to the Har D Har Toy Factory and asked if they would take it. Of course they did, so the boys went home. Unfortunately, their sample model had grown larger, and zapped Doofenshmirtz and Agent P!
