Bryony sometimes, like when she's getting excited about gift wrap.
The titular character Arthur is by no means elegant and worries about almost everything in a hysterical manner, but is an eternally cheery Nice Guy who wholeheartedly believes in the magic of Christmas.
Atlantis: The Lost Empire: Milo Thatch. 115 pounds of weapons-grade adorkable. He's so clumsy-cute, even a princess falls for him. He's voiced by Michael J. Fox, which helps. Early on, Helga lampshades it.
Bambi is portrayed as an eternally wide eyed fawn enchanted by the world around him, as well as adorably clumsy, meek and awkward, especially around Faline. He's also a quiet natured Nice Guy that bulks up into one of Disney's very first Dork Knights as a buck. Even more prominent in the midquel.
Flower is an even bigger Shrinking Violet than Bambi and takes the form of a precious little skunk. He's also the first of the main cast to fall head over heels in love.
Beauty and the Beast: Belle's father. Specifically his face after a hunk of wood clonks him when it's thrown from his chopping machine.
Hiro Hamada. Clumsy, awkward, messy haired and loves to build robots. Instant out-of-universe fangirling. The slight gap in his teeth only adds to his charm.
Baymax behaves rather goofily sometimes, such as the famous soccer ball scene. He also has a tendency to state the obvious, and also things Hiro would rather be kept secret.
Hiro: If my aunt asks, we were at school all day. Got it? Baymax: We jumped out a window! Hiro: No! Quiet! Shhh! Baymax: (whispering) Shhh! We jumped out a window!
Wasabi is a lovable, muscular, Science Hero who's also a complete neatnik.
Honey Lemon. Her character descriptions describe her as "peppy" and "goofy". Then there's her geeky physique, and the almost childlike glee with which she demonstrates her "chemical metal embrittlement".
Fred is self-proclaimed "science enthusiast" and has an obsession with comic book heroes and villains.
Tadashi Hamada. Best proven when seen on Baymax's screen of how happy he is after finally activating Baymax (after 84 tries), prompting him to run around and kiss Baymax.
Even Aunt Cass qualifies, with her childlike excitement and energy with pretty much everything.
Joaquin Emilio Mondragon Jr. crosses into this territory when he's thinking about Maria or talking about his cool mustache.
A Bug's Life: Flik, of the 'socially awkward and yet adorably sweet'-inventor variety.
Cats Don't Dance: Danny. His optimism and energetic dancing and singing make him quite adorable. Also, when he becomes a couple with Sawyer after he realizes what she meant about the new item on his list "Get the girl".
Nod, and even Ronin as well, when mocking Bomba in his and MK's house.
The Fox and the Hound: Tod whenever he's around Vixey. When the two first meet, he goes up to her not having a clue what to say. All he does is smile sheepishly and ask her for her name. He also tries to impress her by saying he can catch a fish. What does he end up doing? Failing of course in the most hilarious way. He also makes up with her over a small argument by giving her a flower. And he doesn't understand what she means when she says six would be just perfect. Talk about socially awkward!
Anna is very clumsy and says awkward things, but she is so nice and plucky that these traits only add to her charm.
The majority of humor provided by Olaf's dorky antics. Singing a song about summer and how he can't wait to see it while not knowing he'll melt, saying awkwardly silly things pretty much every time he talks, and his catchphrase "I like warm hugs" that he says every time he meets someone. Is there anymore that needs to be said?
Hans was essentially just as plucky, awkward, and goofy as Anna whenever he was around her. Then he revealed his true nature.
Elsa when she's excited about Anna's birthday celebration in Frozen Fever and she squeals with excitement at several points.
Kristoff goofily subs the words for his reindeer friend Sven, and gets adorably awkward when he falls for Anna. This is to show that he's generally this in private as well as around humans.
Sven is this when you mix in his clumsiness, love for carrots, and his goofy facial expressions.
Max and Roxanne, the Birds of a Feather who stutter and stammer and behave awkwardly around each other. Being Goofy's son, Max has definitely inherited Goofy's clumsiness and "Ah-hyuck" laugh, making him even more endearing.
Goofy. Thanks to his ditzy, clumsy and awkward, but well meaning and good natured personality and love for his son, Max. Also, he loves everything from the 70s.
But lineage is not the end-all be-all: Max's Fat Best Friend PJ (aka Pete's son) has a baby face, a shy and anxious personality that's even more awkward than Max's, and a voice that hasn't changed—and, as is revealed in the sequel, never did.
Could briefly be used to describe Basil after Olivia's My Parents Are Dead moment. He gets very awkward and tongue-tied before snapping back to his usual self. There's also the scene where he's awkwardly trying to cheer up Dawson. "I say...Dawson, old chap?" with a nervous smile.
Dawson. Slightly clumsy and awkward, but very friendly.
Happy Feet: Mumble dances whenever he's excited, and you can never forget his obvious love for Gloria.
Hercules: Hercules, Especially as a kid. His awkwardness is the contrast between his earnest desire to help and his clumsiness. Even as an adult, he's still sorta awkward. This is more prominent in the animated series, which shows him as a well-meaning teenager making a mess of things rather often as he tries to manage becoming a hero.
Mavis gets quite giddy at the prospect of traveling the world or thinking about Jonathan. She even shows more of this trait in the sequel. When she is on a trip with Johnny, she is so perky and excitable about seeing things she's never seen before. She even thinks she's on national television when she's standing in front of a security camera in a corner store right after trying every single slurpy flavor!
Dracula is a huge utterly sweet dork as a father, and later as a grandfather. In the second film he is completely clueless to the human lifestyle, can barely figure out how to use a cell phone, and tries in vain to to teach Dennis how to be a "real vampire".
Lady and the Tramp II: Scamp's Adventure: The two protagonists from the first movie's son, Scamp. He's a troublemaker, wants a "better" life, and is a big dork whenever he's around Angel. He tries to impress her and be like one of the junkyard dogs but always ends up embarrassing himself.
Ariel when she's human and on dry land for the first time. She takes in everything with an almost contagious amount of childish curiosity and wonderment. And who could forget the scene when she tried to comb her hair with a fork?
Flounder, the cowardly talking fish. He's cute and beautifully coloured in blue and yellow.
Flynn Rider (or Eugene Fitzherbert) is a Deadpan Snarker, Butt-Monkey, gets pushed around by a hot girl half his size? An orphan who reinvented himself after his favourite literary character? That's weapons-grade adorkable right there. He is voiced by Zachary Levi.
Rapunzel has a bit of an overbite, she lisps when she talks at times, hides in her hair during the song "Mother Knows Best" when afraid, Genki Girl, she's overall naive, very pretty and downright adorably Moe.
Toy Story 4 has Forky, who is lethal levels of this trope. He's a Frankenstein of a googly-eyed spork that loves trash, is very neurotic, has an Ugly Cute design, is voiced by Tony Hale, talks Gabby Gabby's ear off about Woody, and falls head over heels for a similar googly-eyed knife in The Stinger.
"Dangit Jim, I'm an astronomer, not a doctor! Well, I am a doctor, but I'm not that kind of doctor, I have a doctorate, but it's not the same thing, you can't help people with a doctorate, you just sit there and you're useless!"
Judy Hopps. She thumps her foot very quickly when she's highly excited or upset, and when she chases after Weaselton who has just robbed the florist she cheers at the chance of getting to apprehend a criminal.
Nick Wilde. For how smug and suave he might be at first glance, Nick can be surprisingly goofy and childish at times, such as when he excitedly starts touching Bellwether's wool or when he gives the "victory toot-toot" after he and Judy have commandeered the Subway car.
Benjamin Clawhauser. He's a sweet, chubby, exuberant, campy fanboy, who also happens to be a feline, giving him an appealing face and expressive friendly tail behavior.
Gideon Grey, as an adult, is very meek and humble around Judy, and also stutters a bit. He also wears a charming pink apron while delivering his baked goods.
