Patchy could be an egghead, seeing as he literally has the head of an egg, but he is not.
He’s not bad, but he is not entirely likeable either. Let’s say he is narrow-minded and hates change. He spends his time head-butting things that bother him, instead of trying to understand them. If you step into his territory, he’ll just chase you out like an angry ram.
Sometimes when he naps, our heroes mistake his head for an egg.
