- Bolt and Rhino freeing Mittens from the local animal shelter, tempered by Bolt's realization that he doesn't have any superpowers to break her out with.Bolt: Are you ready for this?
Bolt: ...Me neither.
- In the deserts of Nevada, Mittens attempts to explain to Bolt that his owner Penny was just pretending to like him as part of her acting job. Bolt knows better.Bolt: Penny is different.
- What makes it even better is that by the end of the film, Mittens knows it too. Penny restores her faith in humanity.
- Rhino calling Mittens out for letting Bolt go on alone. It may be over the top but ultimately what he says is a major part of heroism:Rhino: If Bolt's taught me one thing, it's that you never abandon a friend in a time of need! When your teammate's in trouble, you go! Not caring what dangers you'll face, you go! Not knowing if you'll come back dead or alive... you go! Knowing how deeply the shrapnel will pierce your hide...
- Bolt and Mittens' platonic Falling-in-Love Montage set to "Barking at the Moon", where Bolt gets to experience the fun parts of being a dog for the first time in his life.
- Mittens at the climax when Rhino uses his hamster ball to prop up the falling rubble of the studio so Bolt can get inside and save Penny, grunting stoically "It is a good day to die!" as his ball starts to crack under the weight. But Mittens won't have any of that. She rushes in, opens the hamster ball, and pulls Rhino to safety. What makes this even more heart-melting is that when we first saw her, Mittens was a cynical, I-look-out-only-for myself loner. Take a look at her now:Mittens: Not on my watch, rodent!
- Mindy From The Network displaying extreme distaste of Penny's Jerkass agent, and speaking to her quietly and like an adult. Unlike the others, she doesn't try to give Penny false hope or act like the bond between her and Bolt is something that can be replaced. She just tells her that people are going to start losing their jobs if they can't start filming again, and asks her to be strong and go back to work. It's a refreshing change.
- The real-life super-bark.
- Combines liberally with Tear Jerker, but the moment Bolt resigns himself to the fact that he doesn't know how to save Penny from the fire, he lies down beside her... presumably to die with her. Just the fact that he loved her that much... Thankfully, he remembers the air vent trick shortly thereafter.
- The end credits that feature Penny's new adventures with Bolt, Mittens, and Rhino. The animation is so adorable. Also featured at the end is Dr. Calico (or rather, the actor) posing with the show's director and the d-bag agent.
- Of course we have to keep remembering that the 'bad guys' are actors and bear no real animosity towards the main characters. Still, Dr. Calico's Second-In-Command (who'd ordered her kidnap in the television show at the beginning) went out of his way, staying behind with the two crewmen who tried to get Penny out safely in the climax. When she's carried out, she can see him, ash-stained and still sitting on the ground trying to breathe.
- And before, when Penny tries to run after Bolt right after she gets "captured" in front of him, the director orders the henchmen actors still in the hallway to stop her. Instead of being rough and grabbing her, they're just quick to lean down and put their arms in front of her to keep her from progressing. Even if she's an action star they pretend to do battle with constantly on the show, in real life she's still just a child they don't want to be too rough with.
- Also, when Rhino went after an in-costume henchman who was off the set. When Rhino's ball bumps into his foot, the first thing the guy does is scoop him up off the ground and start positively gushing over him, reminiscing about the pet hamster he had as a child. And when he hears the commotion from the stage, his first instinct is to run there to try and help.
- META: When it was decided that story artist Mark Walton's scratch voice for Rhino would wind up in the final film, the crew decided to break the news to him by bringing him in to record some new lines, one of which was "...and I'm the voice of Rhino". The DVD shows a video of him recording the dialogue, doing a double take when he gets to that line and freaking out in joy.
- Penny, Bolt, Mittens, and Rhino all taking a picture together, shown above.
- The reunion between Bolt and Penny. She hears his barks and immediately runs towards him, and for a few seconds they just hug.
- When Mittens introduces Bolt to the joys of riding in a car with his head poked out the window. The dog is beside himself with happiness upon discovering the experience.
- During the montage accompanying the song "Barking at the Moon," Bolt surprises Mittens with a ball of yarn. She is clearly happy about it. Among other things, it shows how grateful Bolt is for her advice on being a real dog.
