Maybe baby dragons are blond like cats
Olms (Proteus anguinus) look like you took an axolotl & stretched them out. 'Dachshund axolotls', if you will.
They're a cave-dwelling salamander that live deep under the Alps of Central Europe. When floods flushed them out to streams, they were described as 'baby dragons'.
And they lack eyes...
