Doofenshmirtz gives up evil (see Doof 101), Phineas and Ferb adjust to life in school, and Candace thinks Perry is her enemy agent because of all the times he ruined her attempts to bust her brothers. Last Day of Summer needs to become a more complete finale where Dr. I probably wouldn't have come back to watch more episodes if it wasn't for Milo Murphy's Law crossovers helping me realize my duty to write scripts to start a 5th season of Phineas and Ferb in school and the subliminal arc with Candace uncovering Perry's double life between 2 plotlines which initially felt like Agent P was on a different show before Candace caught him.

The episodes I like the most are when Candace is on Phineas and Ferb's side instead of pretending she doesn't like them when she is the only one who cares about zoning permits, because then they get to go on lots of cool adventures together.

Some episodes are more memorable than others, but it's a great under rated series which has some great and memorable moments, like The Chronicles of Meap or Phineas and Ferb Save Summer or Dude, We're Getting the Band Back Together.
