I myself came up with a new idea, seeing as we can put up our own ideas here. It came to me in a dream.

Basically, Phineas and Ferb create a virtual world that one can have fun in, but in order to enter it, you need a special kind of armored suit. Seeing this, the S.A.F. send in a deadly computer virus in an attempt to kill them, but at the same time, Doofenshmirtz fires his new Malfunctioninator, which changes the virus's programming. As a result, Phineas, Isabella, Buford, and Baljeet become more attached to the virtual world, and become evil. Ferb is excluded from this phenonmenon due to his evil spilt personality that you'll have to look up. Anywho, Phineas leads his now evil friends in an attempt to drag the real world into the vitual world, conquering it in the process. It's up to Ferb, D. Ferb, Candace, Irving, and Perry to restore them back to normal before they turn the entire world into data.
