Some of the activities the Octonauts are seen doing when the Octo-Alert goes off are pretty silly, including Peso shampooing a crab, Barnacles testing a snorkel, and Shellington modeling a swimsuit.
Unintentional, but in one of the books, Shellington gains Sudden Anatomy to point at something. However, the way it's drawn makes it look like he's giving the middle finger.
One of the activities shown in "The Frown Fish" is dress-up.
One of the Vegimals helping Tweak into an oversized giraffe costume.
Some of the Frown Fish's costumes include "Magic User Lvl. 20" and "Doctor".
One of the books contains the backstory of the Vegimalsnote The show would feature a very similar scene in "A Very Vegimal Christmas". On this page, one of the notes in Shellington's journal reads "Note to self: look into Hive Mind behaviours."
In fact, this happens a fair bit. Another time was when Barnacles put the marshmallows into the chocolate too early, and Tweak tells him off for it.
The beginning of "The Decorator Crab", where Kwazii is playing with a ball of yarn when it falls into the Octo-Chute, and he yowls and jumps in after it. Really, there is something oddly hilarious about hearing such a realistic yowl come from a Funny Animal, especially one who happens to be a retired pirate.
Likely unintentional, but during the Octo-Alert in "The Whale Shark", Peso reacts to the Octo-Alert with surprise...even though he's the one who sounded it!
When he checks on the immortal jellyfish while driving the GUP-E, he gets this response:
Barnacles: Oh, he's doing just fine.
Kwazii: Except that he almost got swallowed by a whale.
Tunip sounding the Octo-Alert in "A Very Vegimal Christmas" and summoning the Vegimals to HQ. The first time he sounds it, the Vegimals get lost. He sounds it again and they get lost again. Exasperated, Tunip sounds it a third time and the Vegimals manage to arrive there, only to smack into each other and fall over.
At the end of the "Creature Report" segment, Kwazii does a sick backflip, then has an Aside Glance, as if to say "Did ya see that?!".
"Are you hungry?" "There's a monkey?! Where?"
"We should have asked those sailfish for a ride home."
In the Whale Shark episode, after getting Dashi out of the whale shark, she shares some of her pictures of the inside of the whale shark with the crew and comes across a picture of Kwazii in Captain Barnacles' arms.
In "The Crab and Urchin", Captain Barnacles wakes Shellington in the middle of the night, needing info on the creatures they're helping. Afterwards, cut to Shellington asleep at the screen.
Even better; in the French dub, he sounds like he's meowing in his sleep.
In "The Oarfish", when Peso, Pinto and Professor Inkling were looking for the supposed monster, Pinto sees the thing out the window and asks if the monster was long, silver and has red spikes on his head. Then Peso and the professor spot it. Cue to them screaming.
Pinto even decides to sound the Octo-Alert!
In "The Scary Spookfish", we get this exchange:
Peso: (whimpering) Wh-who are you?
Boo: Boo!
Peso: Ah! (ducks down, then comes up) You...s-scared me!
Boo: I'm sorry. You asked who I am.
Peso: Yes I did. So who are you?
Boo: Boo.
Peso: Ah! (ducks down again, then comes back up) Will you please stop doing that?
In "The Slime Eels", after escaping the slime eels the first time Kwazii decides to go back in. The result? Kwazii gets pelted by the slime eels in less than two seconds and gets covered in slime.
In "The Enormous Elephant Seal", When Leon finally wakes up the first thing he does is... wail so loudly that it woke up everyone in the Octopod, except for Dashi who had headphones on.
In "The Sardine School", this exchange:
Peso: How's your head Kwazii? Do you feel dizzy? Sleepy? How many fingers am I holding up?
Hugo and Peso tussling for the Iron Clam in the second round.
In "The Colossal Squid", while trying to break free, Peso is seen trying to bandage a patient, but instead of bandaging it on the injury, he wraps the bandage around his whole patient due to the shaking.
In "The Adelie Penguins" when Peso and Kwazii volunteer to babysit the chicks while Captain Barnacles heads back to the Octopod due to an iceberg moving towards it, both have to deal with their own problems:
Peso having to deal with Flip and Flap who bickers every so often.
Kwazii having to deal with Rocco, who's a daredevil and puts himself in danger.
In "The Coconut Crabs", while racing with the flying fish Kwazii crashes into a coconut with Calico Jack's marking.
Also, in the same episode, Kwazii attempts to open it...by smashing it against the back of the Gup-B denting it in the process. The second attempt, he attempts to open it with Tweak's Octo-Claw, but after a few tries it ricochets off the walls and lands in the Captain's paw.
Kwazii: Once upon a time, Uncle Kwazii and a cute little pufferfish were waiting to be rescued by Uncle Barnacles and Uncle Peso, (chuckles; growing impatient) who are taking forever!
Kwazii looking for Peso who's trapped inside a clam among a bunch of clams.
Kwazii getting taken care of by the Vegimals at the end of the episode.
The Creature Report features a clip of Shellington being attacked by the cone snail...while Shellington stands below it singing.
In "The Water Bears", when a rock falls on Kwazii's head, he thinks that the rover is right in front of him and tries to grab it, only for Captain Barnacles to lift up his visor to reveal it's several feet away.
Peso and then Kwazii fainting due to the foul smell left from the yeti crab.
From "The Hidden Lake"
Shellington getting ahead of the others. Kwazii's even impressed by it.
Kwazii's solution to sleep better? By putting another eyepatch on his other eye. The result? When he woke up he couldn't see a thing and knocks over Captain Barnacles.
After hearing the microbe, Shellington thought he was hearing things.
The rest of the crew trying to balance the Octopod.
From "The Walrus Pups"
A flashback showing a young Barnacles failing to get a badge that involves helping a walrus.
The walrus formula-making montage.
At the end of the episode the walrus babies have returned to their mothers. Their way of thanking Barnacles? Hugging him real tight. It even becomes a photograph.
From "The Baby Sea Turtles"
The whole crew's reaction to how long it will take for the eggs to hatch.
Shellington: It'll take a few more minutes. Or a few more days.
Captain Barnacles trying to get the spinner dolphins' attention by turning up the mic only for the feedback to sound, much to the other Octonauts' chagrin.
Kwazii constantly gettingbonked in the head by coconuts. Highlights includes Kwazii getting hit in the head by said coconut, crashing into a tree and gets hit by another coconut and him getting hit with another one at the end of the episode.
Kwazii: Oh come on! Come on! We haven't got all day!
Shellington: I guess the GUP-C isn't the fastest GUP around.
Kwazii: (is about to pull the lever) Get ready for turbo speed!
Shellington: I didn't know the GUP-C had turbo speed.
Kwazii: It doesn't. (pulls the lever causing the GUP-C to speed up)
Movies
The Caves of Sac Actun
At the beginning of the movie, the Octonauts were planning to surprise some when they come out of the Octo-hatch. When Coddish comes out of the hatch the crew ends up surprising him instead.
There was an exercise involving rings during the swim test. When the Vegimals were bringing out said rings, Coddish holds out a donut, much to Tunip's exasperation.
This exchange after Kwazii's recent pirate tale about the cenotes in the Yucatan jungle:
