...because they blend into the background...

...of their glacial surroundings.

They are referred to as the nameless ones...

But, if you were to tame one...

...you could name it.

Appropriate names might be...

...Frosty,

...Frozen,

...Icy,

...White Fang,

...Snowball,

...or Fred.

You would never name it...

...Fido,

...Tinkerbell,

...Creampuff,

...Snowflake,

...or Cecil.

After naming your Ice Dragon..

...you would need to provide it with proper food and shelter.
