By breeding two parents that collectively contribute only the Blue and Diamond types. The Blue type can also be acquired from any minor type for which it is a component. (True for Black, Rainbow, Gemstone, Tropic, and Metal.) Minor types that have been split from other minor types can also contribute their component types to the type pool.
DISCLAIMER: When attempting to breed the Water Dragon, you may get other offspring instead. Check the Breeding Calculator to view all of the possible results of combining a particular pair of parents.
The Water Dragon is one of only six dragons bought using coins instead of gold.
Unlike most dragons, the Water Dragon can be sold for 1,000 instead of the standard 100 . This is currently the highest amount of coins that a dragon can be sold for.
The Water Dragon, in its baby form, bears a large resemblance to the Horsea Pokémon.
