When first released, they were dropped in the Cave biome and users quickly noticed that they appeared less frequently than other dragons that are dropped during initial release phases. This, along with the "Legendary" title and the fact that they could not breed with other rare dragons indicated that were the first rare dragons to be released that year. After "The Change", they were able to interbreed with each other and other rares, as well as having been moved to their current : * Ice Dragon → * Magma Dragon → * Thunder Dragon →
