When Isabella wakes up she screams so loud that Phineas and Ferb rush over to see what is wrong. She is being carried off by bed bugs. Something had made bugs huge overnight or made them small. Bugs ran the world that morning. Phineas and Ferb knew what they were going to do today. Liberate some humans! They set off, finding out Perry was an agent and Monogram's division is to help them. They go to Bugopolis Capitol. Ferb zaps some really big Big Daddy Long Legs. Isabella was to be rescued from the Bug Overlords. So Phineas, Perry, Carl, Monogram, and the other agents go to the castle to destroy the evil king. The evil king was Doofenshmirtz. Doofenshmirtz knew about Perry's owners now and they were to battle. Guess who won... Perry of course! The bugs shrank and everyone returned to normal.
