These reclusive Groncicles look like they're carved out of the coldest, oldest glacier ice where they're born. Their eggs are great for keeping food cold, but the eggs hatch faster when they're close to snacks.
The Frozen Groncicle appears similar to all other Groncicles in Dragons: Rise of Berk, but it is pinkish purple in coloration and has plates upon its back. They appear to be carved from the coldest and oldest glacier ice.
The frozen Groncicle's eggs are so cold that they can keep items around them such as food cold. However, having a ready food source may cause the eggs to hatch quicker.
