The French comic series Les Womoks, a sci-fi parody series about a bunch of sub-par space troopers, features the Albon, an alien Sugar Bowl civilization of Ridiculously Cute Critters. They seldom come out of encounters with the Womoks without getting the business end of an explosion, yet somehow never lose their ludicrously optimistic view of life, even after their world gets invaded by the setting's Proud Warrior Race bad guys. And after their homeworld gets blown to pieces in the following liberation? They happily live on the resulting Floating Continent Islands, happily enjoying the view.
The Smurf Village in The Smurfs started off as Mordor in the Johan and Peewit comic book story The Flute with Six Holes (later renamed The Smurfs and the Magic Flute), located in what was called The Cursed Land. When the Smurfs got their own series, the village was relocated to a flourishing animal-filled forest until eventually it became a Sugar Bowl.
In the Belgian comicOlivier Rameau, the Dream Land setting of Rêverose ("Pink Dream") is very much this; a happy and fantastic place "strictly forbidden to boring people". It isn't entirely devoid of a dark side, though, as some places are governed by nightmares. Nor it is entirely childish, as evidenced by Colombe Tiredaile, the hero's Love Interest, who has since become quite the sex symbol, thanks to the cartoonist Dany not being shy about drawing her rather au natural.
While theoretically set in our world, Rose Is Rose is constantly on the brink of this. The word "die" has never been used and will never be used, nobody ever suffers even minor injuries, no one is ever more than mildly embarrassed unless they're overreacting, no one has ever gotten a bad grade on their report card, and swatting a fly would be a major Out-of-Character Moment for anyone in the cast. It's slightly disturbing to realize that Sesame Street has gotten darker at times than this ever will. No wonder the main character fantasizes about becoming a Badass Biker so often.
Chapter 59 of You Got HaruhiRolled! deliberately makes the setting of Haruhi Suzumiya into this trope, as a parody of how 4Kids Entertainment would have treated the show had it gotten its hands on it. Haruhi's powers are reimagined as the power of imagination, and everyone else in the SOS Brigade is only there to learn about the true meaning of friendship from her. Taniguchi is chaste and Sickeningly Sweethearts with Ryouko, and even the Anti-SOS Brigade is nice.
Unicornicopia from My Little Unicorn, with its population of winged unicorns and places named after colors.
Pepperland in Yellow Submarine (before the Blue Meanies attack) is a more adult version.
In Wreck It Ralph we get the Sugar Rush race game world where everything is in the form of edible treats, even the cars which are baked, not built.
Films — Live-Action
Heartland USA in Sgt. Pepper's Lonely Hearts Club Band pretty much fits the bill. But once Mean Mr. Mustard steals the magical instruments, installs evil 24 hour Video Arcades, and puts the ultimate sign of evil... a giant hamburger... atop the town square bandstand, everything goes to heck!
The Land of Oz under Princess Ozma, despite periodic threats from outside and certain parts of Oz of being way out there, generally follows this trope. Only when ruled by Ozma, though. If someone else takes the throne, generally you get a Crapsaccharine World (i.e. Jinjur's revolt, the witches running wild).
A Series of Unfortunate Events parodies these quite beautifully with a fictitious novel (or movie if you feel inclined to watch a dreadful movie like A Series Unfortunate Events.) called The Littlest Elf. The reader is told constantly that it would be a better idea to read The Littlest Elf seeing as the book you are reading is unhappy and therefore should not be read by anyone. The Littlest Elf is a running gag that even comes up in Lemony Snicket's "Biography" .
For all its attempts at Darker and Edgier, The Looking Glass Wars really turned Wonderland into one of these. Its capital city is known as "Wondertropolis", there are foods with names like "Tarty Tarts", and even worms are known as "gwormmies". Of course, then Redd takes over and the place becomes a Crapsack World until Alyss returns to dethrone her.
The philosophical novel Ishmael has a bit where the eponymous gorilla attempts to illustrate his main point by making the case for how a world in which people eat other people could be one of these.
Pushing Daisies: An example that is not a kid's show. To balance it out, we get Deadpan Snarkers Lily and Emerson, and a whole lot of murder. Adorable murder.
The Big Rock Candy Mountain, a hobo song from The Great Depression era, describes a more adult-oriented Sugar Bowl with geographical features like a whiskey lake, fauna like chickens that lay hard-boiled eggs, and flora like cigarette trees.
Myths & Religion
The Bible has the Garden of Eden. Plenty of food, all animals are vegetarians (yes, even lions, female mosquitoes, and fleas), no disease, no guilt, and you never die. Also, everyone is perfectly formed and naked. The next world to come will be identical, after this one's inevitable destruction. Many Christian offshoots emphasizing the end of the world have a tailor-made second Earth; fundamentalist sects ignore the nudity, while indigenous versions, such as the Ghost Dance, tend to ignore the vegetarianism. Of course, the nudity pretty much ensures the FCC will never have a children's story in Eden.
In the Dungeons & Dragons setting Planescape, the Outer Plane of Elysium isn't quite this goody-goody, but it's still filled with magical Good-aligned humanimals, brims with bounteous natural beauty, and has an inconvenient habit of turning anyone who stays for more than a week or two into a blissed-out hippie zombie who has completely forgotten why he came there and has no desire ever to leave. This trait is only shared by the planes evil counterpart, the Gray Wastes of Hades, and endless plain of gray dusts. Except that it doesn't make you happy at all. The only reason people don't just lay down and die is that it's futile as most of them are already dead to begin with.
The Madolche archetype from Yu Gi Oh is like this. (Although, while these monsters are cute, adorable creatures with a dessert theme, they may not truly be pacifists. A deck that uses them still requires the player to have them battle the other player's monsters.)
The entire Super Mario Bros series could probably qualify. The Mushroom Kingdom is an idyllic land where Toad people romp happily and the only real problem the kingdom ever seems to have is Bowser's penchant for kidnapping the Princess. A problem Mario consistently resolves in short order.
Played for laughs with Toonstruck's Cutopia, ruled by a giant smiley face.
Hearthome City in Sinnoh is one of the best examples of this trope, having babies everywhere and a park allowing entry only to cute Pokemon.
Maybe. As nice as the above-mentioned places are, Hoenn still has its fair share of problems (its villains manage to cause global warming), and there is a school of thought that some aspects of Hearthome City (much like Sinnoh in general) are not quite what they seem.
Nippon in Okami, once the protagonist gets through with it. However, as she finds it, it's a Sugar Apocalypse.
Team Fortress 2: Apparently this is how The Pyro sees the world. Melee weapons are lollipops, the other team is cherubs, and fire is rainbows. Ammo crates are presents and Health packs are cakes/cupcakes too. Unfortunately, it's a bit of a Crapsaccharine World as well- Mayor BalloonicornMayor?
Don't be ridiculous. Were talking about an inflatable unicorn here. He's the Municipal Ombudsman.
The below quote from The Order of the Stick is some kind of inversion of this trope: the place Belkar is calling "Happy Fun Sunshine Land" is actually a city where it is not odd to walk down the street carrying a corpse with your dagger still in it. He calls it that because he's feverish and delusional from the Mark of Justice curse, and has no idea what's actually going on. The magical fairy part is the only accurate part.
Belkar: Be very quiet, Mr. Scruffy! If we make any noise, the magical Cart Fairy might not take us on the enchanted trip to Happy Fun Sunshine Land!
During the "Dimension of Pain" Saturday story arc, the Dimension of Pain was taken over by a sneaky angel who managed to briefly turn the Dimension of Pain into the Dimension of Fun. The demonic hordes became Care Bear parodies of themselves and the Demon King was turning into Mister Rogers. Fortunately, Lord Horribus returned from his exile and managed to make the angel Fall and become demonic, allowing the Dimension of Pain to be restored to its original evil. Yay!
The "Dimension of Lame" is naturally like this, even if it looks more like our world.
Torg: Why the BLEEP
Yes, the dimension has naturally occurring censor bleeps.
does it smell like flowers down here? Alternate Zoë: It's a sewer, silly!
Sugar Bits has Confectionaria, which is exactly what it sounds like.
Adventures of the Gummi Bears may be an exception to this — or at least not as happy go lucky as the other Disney shows. True, they live in a pretty happy Medieval world standard to the trope, but they are the last remnants of their once great race/civilization on Earth (well, the European part of it anyway) with a certain amount of sadness and Zeerust thrown in as well.
The Magic Roundabout would almost certainly count if it weren't for both Dougal and the Blue Cat and the recent movie
My Little Pony has a reputation for this. Not entirely undeserved, especially in the cartoons for the G3/G3.5 toyline, but the pilot specials, The Movie, and the original My Little Pony and Friends show had the ponies frequently dealing with supernatural threats to their peaceful lives, ranging from rampaging monsters to wicked witches to Evil Overlords.
Not that Ponyville (or Equestria as a whole) is a paradise on Earth. Plenty of species intolerance (the townsponies' reaction to Zecora, the racial conflicts between the three types of ponies depicted in "Hearth's Warming Eve," etc.) and generally bad attitudes (the episode "Putting Your Hoof Down" is chock-full of Ponyville residents acting like real douches) are present. That's not to mention the various monsters that are quite willing to kill anypony they come across (the main protagonist was Taken for Granite offscreen by a random monster in one episode), the occasional but regular nation-/worldwide threats posed by roguegods and cruel dictators, and the gate toTarturus itself less than a day's trot away.
The Smurfs. Gargamel has only succeeded in making one permanent change to the Smurf Village — introducing a female smurf.
The Powerpuff Girls: Him tricks Bubbles with one of these in "All Chalked Up". Clever — who would suspect a place like this of secretly being the creation of an evil, manipulative demon?
In an episode of Project Gee Ke R: Geeker, Noah, and Lady MacBeth are chased into a run-down amusement park. They encounter interactive holograms that adapt to the visitor's "play setting" — with adorably goofy, brightly-colored cartoon bunnies being the default mode. (That is, until Lady MacBeth's short temper triggers their "battle mode".)
The Ro-Bear Berbils seems to be space-colonists from the Sugar Bowl. And true to their nature, they've set up a little piece of Sugar Bowl right in the middle of the mutant-infested swampland of Third Earth. A place filled with houses shaped like giant, pink mushrooms, where candy-canes grow in orchards. They also talk like Smurfs, and all have names starting with a B. Isn't that right, Ro-Bear Bill? Berbil-fruit, anyone?
In the Thundercats UK comic we saw that Sugar Bowl was a deliberate choice. They used to be cyborg-Bears rather than cyborg-Teddy-Bears but they are trying to be Space Amish while still having the Superweapon Surprise technology in their underground facilities to rebuild themselves in their spacefaring warlike image (the Thundercat they showed the hologram of what they used to look like was impressed enough to instantly agree to help them restore their façade of cute harmlessness).
In the Darker and EdgierThundercats: Dogs of War, they are wiped out by the Lizard Men after welcoming the invaders with flowers. This can probably be seen as trying too hard.
The new series' Berbils home is a bit more conservative (though they're are a lot of pink flowers everywhere).
And Berry Bitty City of Berry Bitty Adventures is even more so.
In the Teen Titans episode "Nevermore", between all the nightmarish landscapes that Beast Boy and Cyborg run into is one of these. Complete with floating strawberries. Beast Boy quips, "This must be where air fresheners comes from."
The Dreamstone has the Land Of Dreams, in contrast to the desolate Land Of Nightmares, the former is colorful utopian Medieval World. The majority of it's civilians are perpetually cheerful and sparse on jerkish or cynical traits, usually their only wrathful actions are towards Zordrak and the Urpneys which even then are rather leniant cartoony punishments.
