The Scauldron symbolizes the Tidal Class

Tidal Class dragons live in or near the ocean, and unlike most dragons, they do not breathe fire as their ranged attacks, and although very few can, they rarely do use them. The dragons in this class are generally larger in size than most of the other classes. Hiccup also said that a Tidal class dragon cannot stay out of the water for a long time, but this is false for some of these aquatic dragons.
