History Heartwarming / PhineasAndFerbTheMovieCandaceAgainstTheUniverse

* The final musical number before the credits, "Us Against the Universe", in which almost the entire cast sings about how they have each other's backs. Bonus points for Perry joining in the dancing while remaining out of sight.

* Perry dancing with the others at the end, out of their line of sight. So often, we see Perry joining the boys in pet mode, but seeing him enjoying himself with them as an agent like in the other movie is such a treat.

* After Perry saves him from a fall, Doofenshmirtz is actually touched by the fact his nemesis came all the way from Earth to watch over him and keep him safe.

* Candace's reaction to Super Super Big Doctor's imprisoning of her brothers (and Candace's brothers as well) is to proclaim that she loves her brothers and never wanted to hurt them. Whilst this been shown often in the series, this is the first time that Candace has outright stated it. It's heartwarming to know that despite Candace being obsessed with getting her brothers in trouble, she never actually had a malicious intention behind it nor did she do it out of a hatred towards them.

''[Baljeet, Isabella, and Buford smile]''\\

'''Isabella:''' ''[holding her arm out]'' Yeah! Bring on the [[ItMakesSenseInContext nerve gas puppies]]!\\
''[The gang puts their arms in and break it up]''\\

** Made especially heartwarming when Candace hugs phineas and ferb and says that she couldn't have chosen better little brothers.

-->'''Doofenshmirtz:''' By adulting. ''[referring to Isabella]'' I learned from the best.

* Isabella giving Doof the 'Going Back to Earth' patch.

'''Phineas''': It's all the things that make you the coolest person we've ever met! You kick butt! You rock out! And you can always make us laugh with the kind of laughter that makes you squirt stuff out your nose. Summer would be no fun without you! We just wish you could see yourself the way we see you. You may not be TheChosenOne...\\

* Vanessa giving Doof the 'Going Back to Earth' patch.

** The last time Doofenshmirtz and Vanessa are seen in the film, flying their monster with Vanessa holding her arms around her father's neck. A far cry from
the gothic teenager who was always ashamed of her father from the first season.
* "We're Back" from the credits can been seen as the characters from the show telling all the fans "Hey! We known we've been out of the spotlight for a while, but we're back to make you all smile again!" A huge moment to any fan who grew up loving the show.

** Meanwhile, the Fireside Girls' line in the final verse is a big thank you to the animators.

* When Candace finally gets to open Phineas and Ferb's gift, it turns out to be a "World's #1 Sister" mug that projects all of the great memories they have of her. She was under the impression that she was no one special, but to them, she really ''is'' their CoolBigSis.
