A Birthday They'll Never Forget

by Rockztar

Phineas is planning a special birthday pary for Ferb's 18th, but that night as Phineas and Ferb were driving around, they saw something they'd never forget.

10. Part 10

On the other side of the building was the usual, "Curse you Perry the Platypus!" as once again Doofensmirtz's plan is ruined and Perry flys away.

But this time is different. This time, Doofensmirtz's plan doesn't backfire on Heinz, but instead, on Perry.

So as Perry flys away, with Doofensmirtz calling after him. Doofensmirtz's Junkinator, accidentally fires at Perry's vehicle, as it flew over the Danville Nature Reserve.
