Maybe you don't want to be totally flashy about your royal status.
Anyone regal enough to have whiskers made of Pocky definitely deserves to be crowned the king of all baked goods AND the jungle.
Queen Octopus is pleased by your offering of a jewel-eyed fish, you may proceed to kissing the royal tentacles.
I don't know about having multiple crown cups for your cupcakes. As far as I remember, the birthday boy and ONLY the birthday boy gets the crown!
I don't think you're going to get a real prince by kissing this guy, but he seems like less of a hassle than royalty anyway.
