He looks like a Gronckle made of icicles... maybe he could be called a Groncicle! [src]

The Groncicle is a medium-sized Boulder Class dragon that first appeared in Dragons: Rise of Berk.

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.
The Groncicle stays cool as ice in the toughest battles, freezing opponents with an exploding ice attack.
  Dragons: Rise of Berk  
The Groncicle is an Arctic dragon that is classified under the Boulder Class. Unlike all the other dragons in this class, the Groncicle is quite comfortable in water. While these dragons look a lot like their cousins the Gronckles, their body is more streamlined, undoubtedly contributing to their agility in the seas. To the ignorant, it may look like these dragons lack the ability to cause much harm (barring the fearsome spikes on their chins). But with ice in its veins and liquid nitrogen fire, the Groncicle is not a dragon you would want to upset.
Everything about these dragons remind you of the terrain they love best – they are icy blue and white in color, the spines on their back look like snowy mountains, and the spikes on their chin resemble icicles. But sadly, their affinity to ice and snow means they could never make the Isle of Berk their home. However, you can always visit them in their own land where they may even show you a trick or two. Just remember not to get friendly with them in the water – these dragons freeze the water around them as they swim!

Physical Appearance


Groncicle Egg

Groncicle eggs are oval-shaped with large ice spikes protruding from the surface of it. It is unclear if the 'ice' is real ice or other substances for defense or ornamental purposes. Their eggs are one of the few eggs with well-defined geometrical shapes and are spiky. Those in School of Dragons have flatter spikes.

According to the School of Dragons stable quest "Blast Chiller", Groncicle eggs need to be kept cold, not hot, to hatch.

Hatchling to Adult

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, is covered in snow and ice, and lacks 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.

Titan Wing

Titan Wing Groncicle

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 Wing 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. The Groncicle can use its blast to fill the gaps of broken constructions, as demonstrated in School of Dragons when a juvenile Groncicle repaired a broken bridge.

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 the 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.


  • The Groncicle's name is a combination of the words "Gronckle" and "icicle". According to School of Dragons, the Groncicle was named by Hiccup.
  • Even though the Groncicle is a Boulder Class dragon, it is more appropriate 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.
  • 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 Dragons: 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.
