How did ducky louie get the name ducky?

There seems to be some confusion! There is no widely known character or person named "Ducky Louie."

To help you find what you're looking for, could you provide more context or information?

For example:

* Is this a character from a specific show or movie? If so, what is the name of the show or movie?

* Is this a nickname for someone you know? If so, how did they get the nickname?

* Are you thinking of a different name? Perhaps you meant "Ducky" or "Louie" instead.

Once I have more information, I can assist you better!
