--> '''Kwazii''': ''(defeated; groans)'' I've been suckered.
* Barnacles and Peso scaling up the iceberg to get to the GUP-E.
* Then later on, when the iceberg starts to break apart, they try to stay with the GUP ''while'' trying to keep their balance.
** Highlights include Barnacles using his body as a bridge so that Peso can get to the GUP and him catching Peso when the latter slips and almost falls.

--> '''Dashi''': Back of the net!

!! The Snapping Shrimp
* The fact that a small shrimp can make snapping sounds so loud it can ''stun people''.
* This one's easy to miss. When Kwazii finds Peso knocked out, notice how he takes him back to the GUP-A, he carries his medical kit in one paw and the Peso himself in the other. Looks like Kwazii's [[StrongerThanTheyLook stronger than he looks]].
* Peso's [[TheDeterminator determination]] to do a check-up on the fish that got knocked out with Dashi is both this and [[SugarWiki/{{Heartwarming Moments}} heartwarming]].

!! The Kelp Forest Rescue
* Pinto managing to sneak onto the GUP-C without any of the other Octonauts noticing.
* Peso [[WhatTheHellHero calling out his younger brother for sneaking onto the GUP when he isn't supposed to]]. Although Kwazii is fairly impressed.

!! The Eel Ordeal

!! The Electic Torpedo Rays
* Barnacles tries to get to the steering dock to land the Octopod, but because it's losing power, the podium that reaches the dock only goes halfway. So what does he do? He enlists Kwazii and Peso [[TotemPoleTrench to stand on each other]] so that he can reach the wheel and steer.
** Kwazii and Peso managed to stay balanced ''while'' the captain was steering and ''while the whole Octopod is shaking''.
* The torpedo rays helping the Octonauts power the Octopod.
* Sandy's BigDamnHeroes moment and her helping Barnacles get to the Octo-hatch.
* Barnacles managing to steer the now-charged up Octopod away from the rocks.

!! The Midnight Zone
* A very minor one: To see how the tunnels in the rock connect with each other, Dashi makes a camera small enough for the worm to wear. The camera in general is about the ''size of a coin!''
* Another small one: Peso ''finally'' acknowledges that even though the Midnight Zone is dark, it's not scary at all. In earlier episodes, it's shown that he was not very fond of dark places, especially the Midnight Zone, but now that he's been there a few times, he's finally okay with it!

!! The Mixed-Up Whales
* Kwazii's attempts stop his blue whale friend from crashing into the Octopod.
* The whole crew working together to clean ''and'' fix the Octopod. And they did it in ''less than a day!''

* A minor one: Shellington and Dashi locating which way the storm is heading.
* The trio ''narrowingly'' avoiding a large rock that almost fell on them.
* [[OffscreenMomentOfAwesome Peso helping Sonny deliver the seahorse babies.]]

!! The Enemy Anemones
* The anemones can ''duplicate'' themselves, so much that they can make ''[[CloneArmy a whole army of themselves!]]''
* When Barnacles and Kwazii go back to Octopod, Peso is left to deal with the anemone army. A while later, Peso and the green crab are surrounded by two anemone hordes, [[FromBadToWorse and they start fighting each other]]! About a few stings later, ''Peso'', of all people (or Octonauts in this case), gets fed up with their stinging and ''yells at them to stop!'' That takes guts to get two feuding crowds to stop what they're doing.
--> '''Peso''': '''''[[BigWordShout STOP!!!]]''''' Anemones, please! [[PunctuatedForEmphasis Stop! Stinging each other!]]
** Then when it's revealed that the anemone clans were fighting over territory and that they're fighting over someone else's home, Peso decides that the anemone clans and the crabs should share the rock and stop stinging each other.
** What's even better, is that Peso managed to take charge of the situation ''without the captain telling him to''. ''It was his own choice!'' He took charge of the situation because not only he was pissed off with the fighting, he was worried that the feuding anemones might hurt the crab's friends.
* This one's easy to miss: During the subplot where Tunip and the Vegimals are making pudding for the crew, the machine starts to go haywire and spews pudding on everyone. When everyone is gathered after the Octo-Alert Montage, notice how everyone is covered in pudding ''except for Tweak''. [[OffscreenMomentOfAwesome She must've been able to dodge all those pudding blobs!]]

!! The Crafty Cuttlefish
* [[BadassAdorable The cuttlefish in general.]]
** He managed to trick Peso into thinking he was a rock.
** He can inflate himself to make it look like he grew ''twice his size''.
** And to top it all off he can even make ink blobs ''that look just like him!''
* Minor example: At the end of the episode, Tunip wants to play with the captain's compass again. His response?
--> ''Tunip. Don't even think about it.''

!! The Lost Lemon Shark
* The ChaseScene with the GUP-A and Lemmy.
* The trio lifting Lemmy get off the beach.
* [[EleventhHourRanger Lemmy getting past the hot bubbles to save Peso and the injured starfish.]] This was right ''after'' his nose got better.

!! The Baby Dolphin
* Minor one: When the baby dolphin had a hard time getting his shell back from a lobster, Kwazii comes to help him get it back.
--> '''Kwazii''': ''(to the lobster)'' Go snap somewhere else!
* Kwazii saving the baby dolphin from a shark.

!! The Scary Spookfish
* Even though he didn't know it (and even though the batteries died), Peso managed to take his patient home, using the GUP-E, ''while the GUP's batteries are low''.
* [[OffscreenMomentofAwesome Tweak managing to fix the Hot Cocoa machine]] and calling out the captain for one mistake.
--> '''Tweak''': Next time, remember to put the marshmallows into the chocolate ''after'' it comes out of the machine.
* Boo helping Peso steer himself away from the rocks as Tweak tows him up.
** Kudos to Barnacles and Kwazii pushing ''and'' holding up a heavy, flat rock long enough for the GUP-E to make its way up.

!! The Oarfish
* Even though it was a misunderstanding, Kwazii trying to save Peso (when he thought the latter was getting eaten) is this and [[SugarWiki/{{Heartwarming Moments}} heartwarming]].
* The oarfish itself. He's so big that he needed his body to fit through ''three tanks'' (the Launch Bay, the tank near the Launch Bay, and the tank in the Sick Bay) to have himself checked up.

!! The Combtooth Blenny
* Even though it fails, Kwazii and Peso managed to make a raft to try to get home.

!! The Marine Iguanas
* The other Octonauts helping Kwazii trying to catch one of the iguanas.
** Prior to that, Kwazii catches the culprit but is struggling. So how does he get help? He throws a fork at the Octo-Alert button to alert everyone!
* The marine iguanas helping the crew get out of the seaweed.

!! The Dwarf Lantern Shark
* When Kwazii and Peso are separated from the Captain and Shellington, [[EurekaMoment Peso comes up with the idea to flash their helmet flashlights on and off to get their attention]].

[[/folder]]

[[folder:Season 2]]
!! The Great White Shark
* Peso managing to evade the shark and get to the Octopod, ''while the GUP itself got damaged in the process.''
* Tweak flushing the shark out of the hatch.
* The idea of the Octonauts of using ''[[AwesomenessByAnalysis tonic immobility]]'' to keep the shark at bay so that Peso could bandage his injured fin.
* Kwazii distracting the shark on the Octo-Ski.
* The way Peso gets to the great white to bandage his fin.
** He climbs on the line of the GUP-X (which the GUP itself is ''moving''), jumps onto said shark and uses his bandages to make a makeshift harness and rope (he wrapped himself to the shark) to bandage the fin.
* Kwazii [[BigDamnHeroes saving Peso from the shark]] once he got out of his trance.
* [[HoldTheLine Kwazii and Peso distracting the shark long enough for Barnacles to arrive with food]].
** And when the captain does, Kwazii ''[[SloMoBigAir launches the ski into the air]]'' so the captain can feed the shark fish biscuits.

!! The Sea Snakes
* The sea krait mother managing to sneak onto the Octopod.
* Tweak making snake grabbers and suction suits ([[ChekhovsGun the latter comes in handy for later]]).
* Barnacles tilting the Octopod (using the Octopod's steering wheel) [[CruelToBeKind to keep the mother snake from leaving (due to the Octopod being near a whirlpool).]]
* During the baby snake catching montage, Tweak manages to catch ''three at once''.
* Kwazii and Peso working together to get the last baby snake. ''While the whole Octopod inside a whirlpool''.
** When they do reach her, she loses grip and almost gets swept away by the water. That's when ''Peso jumps off the Octopod to catch her'' and Kwazii, who attaches his tail to the roof and ''also'' leaps to catch Peso and the baby snake, is impressed by his move.
--> '''Kwazii''': (impressed) Brave move, matey!
--> '''Peso''': (stunned) I...I can't believe I just did that!
* Barnacles and Dashi getting the Octopod out of the whirlpool.

!! The Adelie Penguins
* Kwazii saving Rocko from a seagull. ''Twice''.
* During the snowstorm, Peso makes a [[MundaneMadeAwesome tent out of]] ''[[MundaneMadeAwesome bandages]]'' to keep the chicks warm.
--> '''Kwazii''': We'd all be icicles if it weren't for this tent Peso!
* Barnacles saving the Adelie penguin parents and using the GUP-C's ice chipping feature to break a path through the iceberg.

!! The Coconut Crabs
* Kwazii racing the flying fish.
* Tweak making a mechanical claw, capable of ''crushing coconuts!''
* The Octonauts and the Claws working together to crack open Calico Jack's coconut.
* The Octonauts rescuing the young coconut crabs.
** The Octonauts and the Coconut crabs use coconuts as a floatation device for the young crabs to use before Peso picks them up with the Octo-ski.
** Apparently the GUP-X ''can fly!''
** During the rescue, Kwazii almost falls out of the GUP-X (due to rough winds), Claude catches him.
--> '''Kwazii''': ''(to Claude)'' Thanks for the catch matey! And I might add...Yeowch!
** Peso [[BigDamnHeroes rescuing Clarence before a shark eats him]].
* Apparently, the coconut Kwazii found was actually a hollowed-out cannonball made by Calico Jack.

!! The Colossal Squid
* Barnacles' attempt to break the Octopod free from the colossal squid.
* Inkling vs. the Colossal squid.
** Tweak makes a robotic suit for the professor to wear to fight the squid. Bonus points: When he's in the suit, he can control ''the Octopod itself''!
** Two words: '''''[[CoolOldGuy Professor]]'''''. '''''[[TookALevelInBadass Inkling]]'''''. Who knew ''Inkling'' was an expert at tentacle wrestling? He manages to fight off a squid who is ''freaking'' '''''HUGE'''''! And he has some pretty impressive moves that even Kwazii's impressed with!
--> '''Kwazii''': ''(to the professor)'' You're swashbuckling like a proper pirate, professor!
* Barnacles and Kwazii trying to remove the squid's tentacles. While the squid is dragging the Octopod down!
** Special mention goes to the captain lifting ''two at once'' and Kwazii saving him when an incoming tentacle was going to crush him.
* A small one. This conversation when the squid tries to break free from the Octopod when a pod of sperm whales are nearing:
--> '''Colossal Squid''': ''(To Barnacles)'' Stop holding on to me! Let go!
--> '''Barnacles''': ''[[NoYou You're]]'' [[NoYou the one who's hooked onto]] ''[[NoYou us!]]''
* The whole crew towing the Octopod and the squid away from the sperm whale pod. And then rescuing the Vegimals after [[NiceJobBreakingItHero the squid accidentally detaches the pod (Which the Vegimals are in) when he tried to break free.]] [[RuleOfThree And]] ''[[RuleOfThree then]]'' [[RuleOfThree helping the squid get detached from the Octopod]].

!! The Jawfish
* Tweak makes a JetPack that ''works underwater!''
* Both Peso and Kwazii managed to rescue the eggs with their booster packs. But when Barnacles finds an egg in the rocky reef, he manages to get it ''without the use of the jetpack!'' Keep in mind, he managed to get the egg, ''while there were rocks falling everywhere!''
* The trio playing KeepAway with the egg vac (containing the last egg) to keep it away from a trio of hungry lemon sharks.
* Kwazii [[BatmanGambit tricking the lemon sharks into thinking that he tossed them the egg vac with the egg inside it.]] The trick was so convincing, even the ''captain'' thought he gave them the last egg!

* Barnacles managing to get the crabs to calm down and help them save their leader.
* Barnacles and Kwazii going after the Fiddler Crab leader and the GUP-D, through a series of tunnels the GUP made.
** Then when the GUP resurfaces, the two jump onto it and turns it off before it crushes Peso and the rest of the crabs.
* Barnacles and Kwazii trying to rescue Peso and the injured crab from a sinkhole (that the GUP-D made after tunnelling too much underground).
** And when they all fall into the sinkhole, Barnacles spots the Octo-scope, and grabs onto it, followed by everyone else grabbing onto him. Then the captain proceeds to swing ''everyone and himself'' out of the hole!
* The fiddler crabs filling the sinkhole by spitting sandballs into it. Doubles as a SugarWiki/{{Funny Moment|s}}.

!! The Porcupine Puffer
* Tweak makes a portable fish tank.
* The return of the GUP-A's [[{{CallBack}} booster rocket]]!
* Barnacles' attempt to keep the whale shark's mouth open. [[SurprisinglyRealisticOutcome Unfortunately since the whale shark's bigger than him he gets sucked in.]]
* Rewatch the moment where the trio is inside the whale shark's mouth. While the captain and Peso are concerned about going through the sponge wall (which leads to the stomach) and grab onto the gills, Kwazii doesn't care about going through the wall and [[PapaWolf keeps going after Puffy]].
--> '''Kwazii''': I'm going after Puffy!!!
* When Peso nearly drops Puffy into the whale shark's stomach acids, [[HeroicSacrifice Barnacles leaps in Puffy's direction,]] [[HeroicSacrifice where he]] ''[[HeroicSacrifice lands in the stomach acids]]'', [[HeroicSacrifice and throws Puffy to Peso to catch him in the Fish Pack]]. Luckily, he comes out okay!
--> '''Barnacles''': Sorry we can't stay for lunch!
* Kwazii hauling Barnacles, Peso and Puffy out of the whale shark.

!! The Manta Rays
* The whole scene where the crew and Muriel follow the swirling storm.
** Then the chase turns into a rescue when the giant manta gets too close to it.
*** Kwazii and Peso tying themselves and grabbing on to Muriel ([[ItMakesSenseInContext Well not before making themselves slimy first]]) so that the GUP-A can tow them out of the storm.
** Then when the GUP loses power, the crew inadvertently uses Muriel as a sail as another way to get out of the storm.
* The crew and Muriel travelling through an ocean current.
** When they were about to approach a reef, everyone turns on their side to avoid crashing.
* The manta ray feast itself. Dashi was right. It ''is'' worth a few shots.
* A minor one. When the crew gets knocked off of Muriel, Dashi was the only one that managed to stay on.
* Dashi rescuing the guys.
* The remora fish who were teasing Muriel gets some comeuppance. By being grabbed by Kwazii and Peso when both were told to grab on.
--> ''[[DidntSeeThatComing Should've seen that coming.]]''
* The Octonauts getting out of the lagoon by helping Muriel leap out of it.
** Before heading to the surface, Muriel manages to get Dashi’s camera. Keep in mind, she had trouble catching it earlier.
** And when Muriel manages to leap out ''successfully'' and with ''people riding her'', Dashi ''jumps'' off to snap a shot of the crew riding on Muriel!
*** Even better: The shot is used for the cover of National Sea-o-graphic!

!! The Scared Sperm Whale
* Barnacles managing to talk down the sperm whale pod when they [[MistakenIdentity mistook Peso for an orca]].
* Peso helping Simon (a young sperm whale) learn to dive. Doubles as a SugarWiki/{{Heartwarming Moment|s}}.
* When Peso gets trapped inside a giant clam, Simon immediately goes to Barnacles and Kwazii for help.
* A minor one. When the duo dive down into the trench, they didn't put on their deep-sea suits. Guess that trench wasn't so deep.
* Simon ''finally'' having the guts to dive down and rescue Peso! He even ''leaps'' out of the water Film/FreeWilly style!
--> '''Simon''': I ''can'' do this! ''(Leaps out of the water)'' [[AndThisIsFor THIS TIME IT'S FOR PESO!]]
** And that's followed by his BigDamnHeroes moment when Barnacles and Kwazii are struggling to lift the clam Peso's in.
* Another minor one. When the captain goes over to Simon, he inadvertently leaves Kwazii to try to lift the clam and Peso. Kwazii [[Recap/OctonautsS1E19OctonautsAndTheSnappingShrimp was able to lift Peso before]], now he manages to hold something ''twice as Peso's weight'' (even though he's struggling a little)!
* How Barnacles and Kwazii free Peso from the giant clam.
--> '''Barnacles''': [[Recap/OctonautsS1E50OctonautsAndTheGiantSpiderCrab We've dealt with giant clams before.]]

!! The Long-armed Squid
* Both Kwazii and Peso having the nerve to check out an abandoned shipwreck in the deep dark.

* [[BigDamnHeroes The captain coming to Kwazii and Peso's aid when their radio contact got cut off.]]
* The trio working together to the long-armed squid unstuck.

!! The Bowhead Whales
* The fact that Boris and his narwhal friends were able to hold their breath for a long time deserves a mention.
* The bowhead whales rescuing the narwhals by [[RammingAlwaysWorks bashing their heads into the ice wall.]]
* A minor one. Kwazii mentions that he has a ''working'' cannon under his bed.

!! The Damselfish
* Pete, Sandy and Robert having their own ways of evading the damselfish school.
** Pete squirts sand in their faces.
** Sandy has a spike in her fins to keep predators away from her.
** And Robert [[SuperSpeed manages to outswim the school at a]] ''[[SuperSpeed surprisingly]]'' fast rate.
* A minor one. Tweak managing to put damselfish vision in the captain's binoculars.
* Kwazii nearly attacking the damselfish leader after telling Barnacles to scram.
** Doubles as a SugarWiki/{{Heartwarming Moment|s}}: The damselfish leader is seen dissing the captain when the latter tries to get the former to share the algae. No wonder why Kwazii tried to attack the leader. Not only is Barnacles the captain of the Octonauts crew, but he's also Kwazii's ''best friend''. He was just trying to defend him.
* Dashi and Tweak managing to make a camera look just like a damselfish. Complete with damselfish vision, of course!
* The whole BatmanGambit of leading the damselfish leader to the other side of the reef to see that the coral is sick, to get him to share the algae with the other fish.
** First up; Pete, Sandy and Robert distract the school with [[ChekhovsGun previously mentioned skills that they have.]]
** Second, Kwazii drops down from the GUP-B and takes the leader's algae resulting in the damselfish to give chase.
** Four words: '''Peso''' '''''piloting''''' '''the''' '''GUP-B'''! Even though he states that he's never driven a "getaway GUP" before, he manages to drive it in a way that would make Kwazii proud.
*** Special mention goes to how he maneuvers around a big rock and even manages to trick the damselfish school. Barnacles tells him to fake going right, then head left.
*** Peso even says this after the riding experience:
---> "That was absolutely...brilliant!" [[note]] In the U.S version, he says "That was totally...fun!" [[/note]]

!! The Humphead Parrotfish
* The meteor shower.
* Barnacles, Kwazii and Peso using magnets to try to stop the meteor from crashing into the Octopod.
** When that only slows down the speeding meteor, Hattie (the humphead parrotfish the crew encountered before) comes to help them out by getting her school to ''eat up the meteor.''
