Can you translate this sentence for me? "M konn yon planet kote gen yon mouche wouj kou oma." Does 'yon mouche wouj kou oma' somehow translate to 'accountant'?

No.
The word "oma" or "woma" means 'lobster'

M konn   | yon planèt  | kote     |  gen yon mouche  | wouj kou oma.|
I know     | a planet      | where  | there's a man        | red as lobster|
I know a planet where lives a man that is as red as a lobster.
