- Marlin taking on the barracuda. Marlin and Coral are happily moved into their new home, when they realize that their neighbors have vanished. They look up and see the barracuda just.... sitting there. Marlin tries to convince Coral to hide in the anemone, but Coral doesn't listen. She goes for the kids, the barracuda goes for her, and Marlin goes for the barracuda. And for a brief moment, he holds the damn thing off.
- Swim down.
- We've seen everything everything Marlin goes through in the movie. Nigel relays the story to Nemo, it sounds like something akin to The Odyssey.
- Marlin deciding to trust Dory after he nearly got her killed by the jellyfish. The end result? A whale takes them to Sydney and ejects them through his blowhole. Marlin is so impressed that he shouts, "THANK YOU!" in whale.
- All of the fish in the aquarium pulling the dentist's net down so he can't take Nemo. Later on, when Dory's caught in a fishermen net with scared fish, Nemo uses the same idea to save her.
- The part where Gill saves Nemo from Darla, putting his own life on the line.
Gill: (breathing heavily from the oxygen outside the water) "Sharkbait... tell ya dad... I said... HI!" (plops onto the dentist tools, launching Nemo into the sink and right down the drain) Go get em!...
- Equally awesome is how Gill got on the table in the first place: he got into the aquarium's bubble volcano and with Jacque's help, used the force of the bubbles to launch himself halfway across the room into Darla's hair (causing her to drop Nemo's bag on the table). Considering that Gill probably got his scars from a botched bubble-cano launch, putting himself in that position again for Nemo is incredible!
- When Dory and Marlin finally get to Sydney, only to be swallowed almost immediately by a pelican. Marlin has had all he can take at this point and simply decides in the middle of sliding down the bird's esophagus to fight back.
Marlin: NO! I didn't come this far to be breakfast!
- Nemo going to clog the water filter up the second time, even though his first time almost got him shredded to bits. He then gets out, unscathed, much to the delight of the tank gang who thought they were too late to save him.
- Worth noting that hearing about his father's journey to find him gave Nemo the courage to re-attempt the filter clog.
- Also it shows Taught by Experience; the reason why he nearly got shredded was because he went through the filter tube with the fan the first time. The next time he simply exits the way that he came, thus evading the danger.
- Dory GETS HER MEMORY BACK!
- Gill's first appearance when Nemo is stuck in the filter tube:
Gill: Alternate wiggling your fins and your tail.Nemo: I can't... I have a bad fin.Gill: Never stopped me. [he shows Nemo his tattered fin]
- Dory THREATENING the crab with her version of a High-Altitude Interrogation.
Seagulls: Mine? Mine! Mine! Mine!Crab: Wait, I'll talk!!
- Marlin pushing through the jellyfish in order to save Dory.
- Nigel dogfighting a whole flocks of seagulls.
- This film set a new standard for realistic water in CGI. In some parts, when they were cging around shots of real water they used, towards the end, they sometimes couldn't tell the difference between the two.
- Meta: this film serves as Ellen DeGeneres' Career Resurrection, making her a celebrity again after a few years of sinking off the radar. That almost never happens in animation.
