Here's a brand new attempt:
Why did the goose become a detective?
Because it was great at honking the clues!
Explanation: This joke sets up the expectation that the goose is going to have a typical human skill (being good at solving mysteries), but the punchline subverts this expectation by referencing the goose's distinctive sound (honking) and using it in a way that's unexpected and humorous. The humor comes from the image of a goose, which is often depicted as a bit goofy or silly, using its honking to "solve" a mystery, making it a relatable and amusing scenario.
