Sandbuster

The Sandbuster is a Mystery Class dragon that appears in Dragons: Race to the Edge, Season 5. Its name was first revealed via a clip on the Rise of Berk Facebook page.

Official Description
"Like a pirate protecting his treasure, the Sandbuster lurks under the Northern Markets’ shores to guard its gold and sink any trespassers! The many criminals who frequent the Northern Markets are a dangerous lot, but even they know to keep away from the beaches. For years now, the Sandbuster has lived under those shores, amassing a valuable pile of gems and gold in its cave. Territorial and greedy, the Sandbuster burrows sinkholes in the ground that swallow up any humans foolish enough to tread near its riches. The dragon’s only weakness is sunlight, which burns its sensitive scales in a matter of seconds."

- Dragonpedia

"This shifty critter swims through the sand, catching victims unaware and pulls them underground. It hoards loot in great caves, viciously attacking anyone it suspects of thievery! Sandbuster melts down sand and fires molten glass, trapping its prey. Its biggest weakness is sunlight, but it struggles to hold ground against larger dragons."

Egg
A Sandbuster egg is oval, with slightly irregular shape. It is yellow, the color of sand, with green spots, the color of grass. It is similar to the model of the dragon.

Hatchling to Adult
The Sandbuster is a medium-sized dragon. It has a long, snake-like body, similar to the Grapple Grounder. It has a large head with relatively small blue eyes. It has a long neck with sharp rows of spikes. It has four legs, each ending with three sharp claws. The back legs are bigger and more muscular than the fore ones, similar to the Shivertooth. Its wings are big compared to the body. They have two sharp claws on each of them. The tail is very long and has rows of spikes on it.

Titan Wing
A Titan Winged Sandbuster is not very different from the adult. It has bigger spikes on its head, neck and tail. Similar to most Titan Wings, it has red eyes.

Firepower
The Sandbuster shoots very heated sand that becomes glass on impact. However, according to Rise of Berk, it shoots molten glass which solidifies on impact, trapping its prey, similar to how a Death Song does with its amber.

Burrowing
This dragon is able to burrow through the sand, similar to a Whispering Death.

Intelligence
This dragon seems to be quite intelligent as one understood how to protect itself from the sunlight using its blast and then destroyed the only escape Hiccup and the others had.
