how about this; last day of summer, phineas and ferb want to make it the best day of summer, one day that no one will ever forget! mean while doofenshmirtz created an "-inator" to finaly stop perry from defeting him, and also interfiered with Phineas and Ferb's project, but just when things seemed hopeless, perry saved the day. it would include a huge music number featuring almost every character that apeared on the show. just a cancept, but i dont really know what they should do, or what doof would build lol
