Groncicle

The Groncicle is a Boulder Class dragon introduced in Dragons: Rise of Berk and also appeared in School of Dragons. There is a subspecies of Groncicle known as the Frozen Groncicle.

Official Description
"This arctic Boulder Class cousin of the Gronckle is cold blooded! With ice in his veins and liquid nitrogen fire, water actually freezes around him as he swims."

- Dragons: Rise of Berk "The Groncicle stays cool as ice in the toughest battles, freezing opponents with an exploding ice attack."

- Rise of Berk Battle Text

Physical Appearance
Groncicles are covered in snow and ice. Their spines or hunches on their back resemble snowy mountains. They have spikes under their chin which resemble icicles or snow cones.The Groncicle looks like a muscular Gronckle, except that it has a longer body length, covered in snow and ice, as well as lacking a tail bludgeon, instead having a long, streamline tail. The original Groncicle from Dragons: Rise of Berk has a longer tail and a short neck with a low-set head; the Groncicle from School of Dragons has more of a Gronckle form with no neck and a shorter tail, as well as a crystalline skin covering.

Groncicles that have reached the titan wing stage change quite a lot. Their body is darker and there are light blue outlines of what seems to be their liquid nitrogen veins. Their wings have white rings and its edges develop small, spiky icicle-like structures. Titan Groncicles' mouths glow purple and their eyes turn pinkish purple. Also, the icy spikes on their tails and under their chins become larger and thicker.

Liquid Nitrogen Fire


The Groncicle shoots powerful streams of explosive Liquid Nitrogen. Liquid nitrogen can reach temperatures close to -321 °F or -196 °C. This can potentially freeze their victim to death, meaning It also has the coldest blast of all the dragons.

According to the Dragon Eye, the Groncicle's ice breath is amazing as very few dragons have it. The blast also has the ability to condense the water vapor in the clouds, causing it to rain or snow.

Freezing Water
The Groncicle is able to freeze water around it while swimming. This is probably because the ice in its vein causes the water around it to lose heat and freeze, though the reason for the Groncicle's uncanny behavior is unknown. One possible purpose is to freeze and trap their aquatic prey in water.

Behavior and Personality
Groncicles eat snow to generate their ice breath. They will also use soft snow and this cold breath to build their nests. They are seen to live in social settings with one another. Groncicles are a peaceful, friendly, non-aggressive species. Having been the first dragons to ever be peaceful with humans (with the ancient Vikings of Icestorm Island), they are naturally kind with people. Despite their cold natures, Groncicles are big softies. They are a helpful race that allies to those who treat them with respect. But they do not respond kindly to a lack of respect and should not be taken lightly. Their affinity to ice and snow means they must remain in cold environments or they will overheat. Summer in Berk, for example, is too warm for them.

Interestingly, it is revealed in School of Dragons that Groncicles like smoothies made of a mixture of arctic gentian, arctic poppy, and pumpkins. It's indicated that no other dragon, or human, enjoys this strange drink.

Dragons: Rise of Berk
This dragon first appeared in Rise of Berk, along with its Titan Wing form, where the Frozen Groncicle was introduced.

School of Dragons
This dragon also made its way to School of Dragons and was made available during the Icestorm Island expansion pack.

Trivia

 * The Groncicle's name is a combination of the words "Gronckle" and "icicle".
 * Even though the Groncicle is a Boulder Class dragon, it is more sensible to be put in the Tidal Class because, the description states that it swims, and in the Arctic regions, water and ice are everywhere, meaning that it is a frequent swimmer.
 * It is the only known water-based Boulder Class dragon.
 * The Groncicle's egg looks like a geometric ice-like shape similar to the Shivertooth's and the Sweet Death's egg.
 * According to School of Dragons, the Groncicle was first named by Hiccup.
 * The Groncicle's egg has a similar appearance to the Orb of Frozen Futures. Some people, like Trader Johann, can confuse the two of them.
 * This makes the Groncicle the second dragon whose egg is confused with something else by Vikings, the first being the Changewing.
 * The Groncicle seems to have no actual teeth in Rise of Berk. But teeth that resemble a Gronckle's were added in School of Dragons.
 * Groncicles in their battle armor are the toughest normal species of dragon.
 * The Groncicle seemingly has the coldest fire in the dragon world, this would make it a good rival to the Fireworm Queen as they have the hottest fire in the dragon kingdom.
