He appears very briefly. He is a background character. Riverfrost appears in Rainfeather's Story 14. Might do another appearence deeper into the series... o.o

Wait what chapter was riverfrost in?

It's a horse creator game called "Doll Divine Fantasy Horse Maker"

Again is there a computer program or something that you do it on????
