If you could provide more context or explain what you're trying to convey, I might be able to help you better. For example, are you trying to:
* Translate a phrase? Please provide the original phrase and any other relevant information.
* Ask about a Dutch idiom? Please provide the full idiom and any context.
* Create a phrase with a specific meaning? Please explain what you want the phrase to mean.
Once you provide more details, I can help you better understand the meaning of "Haas moet doen what doen?".
