Meaning of にまでなる


> まあっ、なんて欲ばりな女だろうね。あんたみたいな犬がねぇ、くわえてた肉を池におっことしたって話が、童話 **にまでなってる** よ。  
>  Come now. What a greedy girl. The story of a dog like you which dropped a
> piece of meat it was holding in its mouth into the pond **is becoming a
> fairytale**.

I'm sure I've got the end of this translation wrong. I don't understand
にまでなってる in this sentence.

Also, the whole sentence is bizarre. I guess this is a reference to a Japanese
folk-tale. I know it's off-topic but a quick summary of what this sentence is
referring to would be helpful.




にまで in this sentence is used in an emphasis of the dimension. 童話にまでなってる is
translated as "The story even become a fairytale." and "The story do become a
fairytale."

For example, 彼は大臣にまでなった.(He even became a minister. He did become a minister.)

And I guess this story isn't a reference to a Japanese folk-tale but Aesop's
Fables like "The dog and its reflection.
