History VideoGame / DragonVale

* HundredPercentCompletion: It depends on the player as to how far they take this. Some players are satisfied with only collecting one of every dragon, while some will not stop until they have every normal dragon, twin, pedestal, twin pedestal, and decoration in the entire game. The game rewards getting every dragon by having the Dragonarium breathe fire. After collecting all the twins, it will breathe blue fire.

* TimeMaster: Kairos, the first legendary dragon of the game, can accelerate any event in the game by a few hours (breeding, building, etc.)

* FloatingContinent: Your zoo is located on a floating island. As you level up, you can get a whole archipelago of islands for your zoo plus the crystal-only epic breeding island.

* LastLousyPoint: The Leap Year and Blue Moon Dragons. They're not required for any achievements or anything, but most holiday dragons are only available for a few weeks a year. These dragons are instead only available for a matter of ''days'', and only show up every ''three or four'' years. (That said, the game has had at least one event where for a month or two every dragon was made available.)

* ElementalPowers: Most dragons are classified in eight elemental types: GreenThumb, PlayingWithFire, DishingOutDirt, AnIcePerson, ShockAndAwe, MakingASplash, BlowYouAway, and ExtraOreDinary. LightTheWay and CastingAShadow were added to the game in late 2013.

** InfinityPlusOneElement: Originally Rainbow, Sun, and Moon; which had their own habitats and couldn't be bred with dragons of other types. Several other elements were later added to this level; but by then they had been surpassed by Gemstone Dragons, which have their own island, can't be bred period, and generate crystals instead of coins; and later Galaxy Dragons, which also have their own island and can only be bred through [[SocializationBonus cooperative breeding]].

* GoldMakesEverythingShiny: All of the treasure dragons, especially the Gold dragon, which have their own special habitat which is full of gold coins. Also the most expensive pathway in the game is gold, which costs a whopping 7500 gold pieces ''per tile''.

* GoldMakesEverythingShiny: The Gold dragon, one of the rarest dragons to breed in the game, which also needs its own special habitat (now shared with a few others now). Also the most expensive pathway in the game is gold, which costs a whopping 7500 gold pieces ''per tile''.

** ElementalRockPaperScissors: Most elements have a opposite, which they cannot be bred with (fire and cold, or earth and air, for example), unless you create a hybrid first. They will also be affected negatively by the Boost item for their opposite element.

* AprilFoolsDay: The Motley dragon was released for April Fools Day, as it can be bred from any breeding pair at all, even if its elements are not included in the breeding pair. This leads to players accidentally breeding many, many unwanted dragons.

* SocialisationBonus: The Co-op breeding Cave allows you to breed one of your dragons with a friend's dragon, which allows you to obtain expired limited dragons you would not normally be able to get. Galaxy Dragons are never available for breeding normally, so this is the only way to obtain them. Breeding in the Co-op Cave is also the only way to get the rare and highly sought-after Twin Dragons.

* EverythingsBetterWithRainbows: One of the rarest dragons available is the Rainbow Dragon. Taken to the extreme with the Double Rainbow Dragon.

* HybridOverkillAvoidance: There are many crossbreed dragons, but when hybrid dragons breed their offspring will usually have two of their parents' types; no more. Though there are a couple of exceptions when it comes to holiday-only dragons (the Panlong Dragon has the four classical elements; the Love Dragon is fire, lightning, and plant). The Rainbow Dragon is also implied to have all eight types at once.

* InUniverseGameClock: Everything in the game runs on real time. Dragons earn coins per minute, food crops take between 30 seconds and one day, depending on amounts, breeding dragons takes hours, as does hatching eggs and constructing habitats. There are also a ''lot'' of dragons based on the calendar and related astrological events (the leap year, the solstice and equinox, the blue moon...).

* PaletteSwap: The Blue Fire, Frostfire, Malachite, Plasma, Current, Leap Year, Sandstorm, and Ironwood dragons are recolors of the Fire, Cold, Metal, Lightning, Water, Rainbow, Air, and Plant dragons, respectively. The Dodo dragon has the same body as the Earth dragon, but has horns on its head and wing-like feathers on its back rather than spikes.

* SocialisationBonus: The Co-op breeding Cave allows you to breed one of your dragons with a friend's dragon, which allows you to obtain expired limited dragons you would not normally be able to get. Galaxy Dragons are never available for breeding normally, so this is the only way to obtain them. Breeding in the Co-op Cave also gives you a chance to get a rare and highly sought-after Twin Dragon.

** In 2012, Backflip Studios claimed they would be releasing an 'invisible dragon' on the first of April, accompanied by a false screenshot. The dragon was never released in the game, however, it was made available on April the first, 2017, in ''[=DragonVale World=]''.

* SeldomSeenSpecies: The Cave dragon seems to resemble a spider, but it bears a greater resemblance to [[ https://en.wikipedia.org/wiki/Amblypygi amblypygi]], a type of cave-dwelling arachnid.

* [[ArtisticLicenseChemistry ArtisticLicenceChemistry]]: The Acid dragon is a metal hybrid, even though many metals are bases, meaning they can neutralise acids.
