What kind of medicine does DOCTOR EGGMAN practice?

Anti-hedgehog medicine and turning animals into evil robots. It's the best kind of medicine for a fantastic scientist such as myself!

Are you implying that hedgehogs are diseased themselves?

Hedgehogs aren't diseased, they are the disease. Trust me, I've had one for the last 28 years.

What exactly did they do to be a disease?
