The main challenge of creating My Little Egas Moniz was figuring out how to represent his debilitating gout. I figured a nice bruise color and a few bandages would suggest his physical tenderness. Incidentally, did you know the condition got its name from the word meaning "drop" because it was originally thought to be caused by an accumulation of humors? Which makes sense in a way, because gout most often strikes the feet, where humors would pool. Egas, however, was special: his gout mainly afflicted his hands, which was particularly terrible for him because he was a brain surgeon. I believe that he never actually performed a lobotomy, despite having invented the procedure. He just gave orders while guys with working hands moved the knives.
He had very sleek dark hair so that was easy to ponify. And in answer to your question, that's his Nobel Prize.
