What Is King Yemma's Hat?

[Sovran Nila]

What exactly is King Yemma's hat supposed to be?

Maybe he is hiding his baldness underneath that hat

Covers his head so he looks less homeless. Also his desk is reaply tall so wjen you look up at his desk you can't see him easily if you're short like Krillin, but you can see the hat.
