Mnemonic symbol: this character looks like something (a head?) on two legs. I'll just represent it by a cuttlefish (只). James II of England (zh) has been in the space station (Ø3) as the only (只) one for too long and went mad. He thinks he's holding a mandarin (口), but he's just about to bite into merely (只) an eight ball (八). On the top of his head is a cuttlefish (只) he mistook for a hat.
