I want him to visit my house, like the Easter Bunny. Instead of putting out carrots and baskets the night before, you leave little decorated paper mononokes out on Medicine Seller Eve. When you wake up, you run into the living room and the mononokes are gone, replaced by... I dunno, throat lozenges or something. Then you know he's come by in the night, and you stay in your pajamas to watch all the Kusuriuri Day specials on tv, where he goes on gay claymation adventures or something.
