Angry Birds X: The Fine-Feathered Movie/Tropes/Heartwarming

* This film is a love letter to the angriest birds in history, and it shows with the focus on Bomb and the fellow members of his flock. Plus the easter eggs to various Angry Birds media throughout the film are done in a subtle but clear way.
* The other pigs on Piggy Island rebuild and reopen Edgar’s restaurant, Chez Piggy.
* Just... the friendship between the Flock. They have a genuine loving friendship. They're together and care for each other as a surrogate family of birds. This film shows that Bomb really does see the other birds in his flock as family.
* It's a small detail, but among the many, many cameos you see is the Relationship Upgrade between Eddy and Shareena Wickett, of all people. Unexpected, but so cute!
* The scene where Winnie assures Bomb and his flock that they'll get their eggs back.
*Combined with Tear Jerker; the scene where Roger Rabbit and Bomb pause to look longingly at a portrait of the former's dear friend, Eddie Valiant. For added feels, the scene is accompanied by a brief piano rendition of "Eddie's Theme", and played by none other than Alan Silvestri. Bomb: Hey, Roger. He would be proud that we defeated him like he did..Daffy: (is heard tearing up offscreen) Okay, can we make this less emotional, please? We gotta go, you guys! The toons are in South Beach!Roger: Be right there, Daffy! (turns to the portrait and gives off a sincere smile) Gotta go for a group picture. But thanks for everything, especially clearing my name, Eddie..
* Hal finally getting the recognition by all toons he deserves for being the heart of the Flock. Throughout the whole movie, Hal keeps the rest of the Flock grounded so that they don't forget the little things to take care of each other.
* Hal and Sidney's growing, if subtle, relationship throughout the movie.
* The whole army of Toons ready to stand up against Baron Harmful, just to protect the Flock and their homes.
* Hal being so determined to save his Flock from Edgar's piggy army. Just goes to show how Hal is still the Nice Guy we know and love.
* Combined with Funny; The group picture of the pigs, the Flock, and all of the toons is full of easter eggs and sweet moments, including:
** The Cheshire Cat and Blue playing with the yellow ball with a red stripe and blue star from Blue's Clues.
** Scooby-Doo and Shaggy sharing each a Super Shaggy Sandwich (a double triple-decker sardine and marshmallow fudge sandwich).
** Garfield giving Fifi La Fume a slice of his lasagna.
** Lucy van Pelt finally giving Charlie Brown a chance to kick the football... and NOT pulling it away before he can kick it
** Lynn Loud being very excited to see her heroes, the Angry Birds, with Dipper Pines calming her down.
** Shareena Wickett kissing Eddy on the cheek, with Ed and Double D smiling at them and Lee Kanker kindly leaving them alone.
** Pinkie Pie, Luan Loud, and The Blues entertaining themselves by throwing pies each other.
** Bugs Bunny and Mickey Mouse shaking hands with each other.
*The rousingly wacky and jazzy Looney Tunes-like rendition of "Smile, Darn Ya, Smile!" is essentially the film's version of "Never Give Up Hope (Finale)" from Wakko's Wish as all the characters sing to prepare for a group picture. Highlights include:
**Hal, Luna, Schroeder, and surprisingly Squidward start the song with the instrumentals.
**Bugs Bunny and Mickey Mouse begin the sung part of the song.
**This is followed by characters like SpongeBob, Timmy Turner, Michigan J. Frog, Jimmy Neutron, and Danny Fenton joining in.
**The Cheshire Cat, from Disney's 1951 adaptation of Alice's Adventures in Wonderland, taking Blue's paw as well as that of Ren Höek when singing his part in the finale.
**Alvin, Simon, and Theodore take over from the Cheshire Cat, and receive musical instruments from Dave Seville too.
**Roger Rabbit finishes the song as everyone joins in as thier picture is taken.
*Let's face it, the end of the movie is loaded with heartwarming moments:
**Red, Bomb, and Chuck, to an extent, each take turns telling the entire crowd of Toons how vital a member Hal is, and how they went through in the movie.
*** In Red's case, Hal helps Red ease his anger issue, and encourages him to be more social to others not from Piggy Island or Toontown.
*** In Chuck's side, before Hal first met him at summer camp, who didn't had any real friends and had abandonment issues, like Hal, Bomb, and Red, Hal befriended him. Aside from his mom, Chuck was all alone for most of if not all of his life. Chuck even goes so far as to point out the only thing Hal is guilty of is being the best friend he could ever have, having risked it all to protect the flock he loves as a family.
*** Bomb's speech for Hal being not only the brains of the Flock, but also the heart of the Angry Birds. Like Red, John DiMaggio makes an excellent delivery.

* When casting Velma Dinkley, they got Mindy Cohn, who had voiced Velma since What's New, Scooby Doo, to reprise the role, three years since her last appearance as the character, Lego Dimensions.
* The fact that Warner Animation Group credited the animators for the animation of the film is so sweet.
