History VideoGame / Dragonvale

** Moonstruck dragons have green mothlike wings and patches of fur resembling moth antennae. They're extremely affectionate, and spend much of their time gazing distractedly at beautiful things.

** The Rift update introduced Rift versions of all the normal hybrid dragons, and some of the Halloween-themed dragons. As well as their normal elements, Rift dragons have an elemental 'trait' which is separate and unrelated to their type. This means to achieve 100% completion, a player must breed every type of dragon with each of the ten possible traits. There's also the extremely rare Twin Rift dragons, which can only be obtained through mystery eggs. However, these are so difficult to get, most players don't count getting them as part of 100% completion.
* HeadSwap: The Clover dragon, which has the Flower Dragon's wings and body with minor alterations, but an original head and tail tip. The Solstice dragon is a two-headed version of the Sun dragon and the Blue Moon dragon has a horn on its head and a full moon on its tail rather than a crescent moon.
* HolidayMode: The islands change with the seasons, being snowy in winter and green in summer. There are also season-themed decorations for the islands and holiday-only dragons which can only be bred in the month surrounding their respective holidays. In fact, exaggerated, considering the list of holidays and events that get their own dragons include [[EasternZodiac the Chinese Year of the Dragon]] (the Panlong Dragon), the leap year (Leap Year and Double Leap Year dragons), several for Valentine's Day (Love, Moonstruck, Thorn, Rose, Stoneheart, Rosegold, Ambrosia, Cuddlewing, Surprise, Melancholy, Delight, Serenity and Ire dragons), St. Patrick's Day (Clover Dragon), April Fool's (Motley dragon), Easter (Monoliths 1-6, Plateau, Pond, Tulip, Stoneshell, Tansy, Cumulus, Chrysalis, Duskwing, Glowwing, Lacewing, Marbletail, Starwing, Swallowtail and Bloom) Earth Day (Terradiem dragon) and Arbor Day (Arbor dragon), the Japanese {{Cherry Blossom|s}} festival (the Sakura Dragon and Sumi dragon), Mardi Gras, Mother's Day (Bouquet dragon) and Father's Day, Deaf Awareness Month (the Butterfly Dragon), the solstice (Solstice dragon), the equinox (Equinox dragon), 4th of July (Firework dragon) and Bastille Day, the Summer and Winter UsefulNotes/OlympicGames (the Olympus Dragons and Victory Dragon), Halloween (Bone, Ghost, Nosferatu, Bog, Decay, Garden, Ortreat, Spectre, Thicket, Trick, Lycan, Nether, Zombie, Nightbloom, Pharaoh), Christmas (Gift, Holly, Mistletoe, Regift, Reindeer, Trinket, Dazzling, Flicker, Lace, Ornamental, Ribbon, Snowflakes 1-5, Tinsel, Verglace, and Twinkle) the blue moon (Blue Moon dragon), eclipses (Solar Eclipse and Lunar Eclipse dragons) and the 2012 end of the Mayan calendar (the Apocalypse Dragon). Plus each month and season gets its own Gemstone Dragon, based on that month's birthstone. Each season also has two seasonal dragons each (Winter and Seed, Spring and Sprout, Summer and Leaf, and Autumn and Berry).

* ColorCodedElements: Each element has its own color: green for Plant, red for Fire, brown for Earth, light blue for Cold, yellow for Lightning, blue for Water, purple for Air, orange for Metal, light yellow/white for Light, and dark purple/black for Dark. All of the basic element dragons come in these colors, save for the Air Dragon, which is dark blue and cyan. This also allows players to identify what kind of egg they have. The primary color scheme of hybrid dragon eggs corresponds with its main element and the pattern on the egg corresponds with its secondary element. For example: Lava, a Fire/Earth hybrid has a red egg decorated with small stone chips.
* DarkIsEvil: Many of the Dark hybrid dragons are based around more sinister concepts, for example, the Ruin dragon, the Nightshade dragon, the Miasma dragon, and the Crypt dragon. They also tend to be more UglyCute rather than [[RidiculouslyCuteCritter Ridiculously Cute Critters]] like most of the other dragons.

* ElementalPowers: Most dragons are classified in ten elemental types: GreenThumb, PlayingWithFire, DishingOutDirt, AnIcePerson, ShockAndAwe, MakingASplash, BlowYouAway, and ExtraOreDinary. LightTheWay and CastingAShadow were added to the game in late 2013.
* 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. Initially, they were also affected negatively by the Boost item for their opposite element, though this has now been removed.

** Butterfly dragons, created by breeding an Air-aligned dragon with a firefly dragon, have colorful butterfly wings and no forearms.

* EverythingsBetterWithRainbows: The Rainbow Dragon. Taken to the extreme with the Double Rainbow Dragon.

** The Sulfur dragon is mentioned to have a strong odour, but in real life sulphur is odourless.

''[=DragonVale=]'' is a park sim along the lines of ''VideoGame/FarmVille'' available on [=iOS=] devices. The player runs a zoo/conservatory for dragons, and they must purchase elemental habitats and dragon eggs, as well as breeding new species of dragon. Dragons collect coins based on their type and level, and levels are increased with dragon snacks (which in turn cost coins). The game is notable for its absolutely immense number of dragons and quirky FlavorText that often makes refences to pop culture.

* AntiFrustrationFeature: A growing number of dragons (about 50% of the total, and a larger majority of dragons that aren't esentially ComMons) are only obtainable under certain dates or events. Some, like those celebrating yearly holidays, return once a year, but others, like those created for each anniversary, only really have their event once. To help players achieve HundredPercentCompletion, there are two features;

** Two, The Daily Rewards system tracks each day a player visits their park, and every hundredth day gives a Wish that can be redeemed for ''any acquirable in the game''. This is especially helpful for the Monolith and Snowflake dragons, which can only be bred from other Monolith and Snowflake dragons and as such aren't helped by Bring 'Em Back.

* 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.

** Taken UpToEleven with the introduction of Twin Dragons. These are rare versions of normal dragons, which have a low chance of being created from breeding in the Co-op Cave. Considering how rare even normal versions of some dragons are, this can make getting all the twins virtually impossible.
