Alternate Character Interpretation: One of the implications of how the other penguins behave around Rico is reminiscent of that of an adult with a learning or developmental disorder - when he loses control they seem just as concerned that he might hurt himself as others. Significantly, in "Kaboom And Kabust", Skipper's lines describe serious concern for Rico's safety, with the penguins all implying that he's not fully responsible for his own actions, while Julien's behaviour in this episode is highly manipulative, taking advantage of Rico for his own personal amusement. Julien even describes himself as Rico's enabler at one point. An enabler is a person who encourages or enables negative or self-destructive behaviour in another.
Base-Breaking Character: Doris. Deliberate heartbreaker, or a flawed character whose fickle nature has her making the same mistakes over and over, but still likeable enough?
Bellisario's Maxim: The penguins can't read and need to consult Phil and Mason to read for them. Except for all the times when they clearly can read when it's important for a joke.
Big-Lipped Alligator Moment: Subverted in "Eclipsed." King Julien gets a big, long musical number about his "congaga." Although this musical number has all the trappings of a BLAM in its over-the-top, out-of-nowhere-ness (keep in mind the show almost never does musical numbers), it sets up the plot.
Cant Unhear It: Jeff Bennett and James Patrick Stuart's performances as Kowalski and Private were so well received that many people thought they should've been brought back for Penguins of Madagascar instead of Chris Miller and Christopher Knights.
Cargo Ship: Julien has repeatedly flirted with Rico's Miss Perky doll and has had some slight narcissistic Ho Yay with @Lemmy', the robotic Lemur. Kowalski had a thing for Officer X's animal control van, and the sentient gel-o that is Jiggles.
Crazy Awesome: Rico, obviously. But rest of the penguins, except for maybe Private, count as well. How else do you call a badass military officer who is extremely paranoid about everything and a Mad Scientist who is also a Badass Bookworm?
The John Travolta Pigeon in "in the line of doody" wanted to poop on the parks and recs manager... for trying to get rid of all the pigeons around all the parks. Pigeons are being treated as Always Chaotic Evil while the Penguins support this man.
Officer X. It's hard to argue with his grudge against the penguins given the constant scorn and public humiliation he goes through because of the penguins while he's doing his job
All the songs in Return of the Revenge of Dr Blowhole.
Fandom Rivalry: When "In the Happy Little Land of Hoboken Surprise" took the Emmy Award for Best Original Song, the Brony community wasn't pleased as it won against two of FIM's songs.
"Funny Aneurysm" Moment: All the jokes in "The Hoboken Surprise" about Hoboken being a terrible place are a lot less amusing after Hurricane Sandy. Or Hurricane Irene, for that matter (the episode literally aired a week before the latter storm hit).
Genius Bonus: In Cute-astrophe Skipper says he can "smell an anecdote from 1.6 klicks away". One klick equals one kilometer. One mile is 1.6 kilometers. Even in klicks Skipper hates the metric system.
Possibly one of the most triumphant examples in Western Animation; in "Hello Dollface", Private is berated for his love of Lunacorn toys, because it's meant to be a girl's toynote Note that this is never actually stated. The actual problem is that the Lunacorns are too soft for Skipper's taste; the words girl toys were never used. When did this episode air? October 9, 2010. ExactlyONEday later...
To say nothing of the fact that Tara Strong voices the Lunacorn doll.
Hans mentioned that he kissed Skipper's sister but Skipper claimed that he doesn't have a sister. Given the similarities Skipper has with Clover, one would wonder what would Skipper say if he met her◊.
Ho Yay Shipping: The show has its own Ho Yay page as it is, but the level of subtext between Kowalski and Rico is the highest thanks to how often they are paired.
One episode features a poison dart frog with such potent venom that the slightest touch renders one temporarily paralytic and with a comical rash; he uses this power to keep all the other animals at his pettiest whim. Private eventually knocks up a protective suit that will allow him to give the slimy little chap a nice big hug. Barry contemplates if he's really a jerk, but decides that yes, he likes hugs more.
Officer X. His antagonism toward the penguins is because they thwarted him in the process of doing his job.(In their defense, they WERE protecting someone they considered a friend) While you can't blame the penguins for trying to keep themselves safe, anytime he's not opposing the penguins, he's really just doing his job, and his "reward" for this is constant public humiliation and scorn.
King Julien, hands down. Not only do fans pair him up with Mort and Maurice, but every single penguin too. The show provides plenty of chances. It's only a matter of time before they pair him with himself.
As the closest thing the show has to a female lead, Marlene has been paired with every character, though pairing her off with Skipper is by far and away the most popular.
Despite the fact that Marlene is the only regular female character, and despite them having nothing in common, Skipper and Marlene is still far and away the most common fanfic pairing for them...
... when the penguins aren't being paired with each other.
Ship Tease: Despite how much Ho Yay Rico has with Kowalski, he still gets some tease with Marlene, with the suggestion that Marlene actually likes how excitable he can be, such as in "Jungle Law" when he uses her as a boomerang and she finds it fun, and "The Otter Woman" when he thinks 'Arlene' is attractive. Since Rico is the only Penguin who doesn't have a canon living girlfriend, this has resulted in a small fandom for those who want to try something new.
Squick: In Friend-in-a-Box, Julien happily tells Kowalski that he never learned the Potty Dance, because as king he's entitled to go wherever he happens to be at the time. Kowalski backs away from him with a disturbed look.
Ugly Cute: Rico. While he isn't that ugly, he is designed in a slightly more cartoony manner than his already cartoony comrades and he has a flatter face, a scar, bigger beak and double chin... and yet he is absolutely adorable, mostly because of how expressive he is.
