If you're referring to the sound similarity between the words "haddock" and "headache," then I understand your point.
Indeed, there is a phonetic resemblance between the two words. However, it's important to note that haddock is still a fish species and not directly associated with headaches or any medical condition. The similarity in sound is coincidental and unrelated to any ailment or discomfort.

It's a haddock, nothing but a haddock

Haddock is still a fish species, still no change there, consequently DO NOT adjust your haddock status indicators
