I read that the question marks over a town you finish it you should get a mystery field event. Please if that is not the way what is?

no those are optional quests, side quests, mystery field events is when you grow a certain plant with a certain seed and fertilizer, and as soon as you get it if it's the right combination a cinematic will take place, like the love flower(can't remember combination)

Does Anyone out there the some or all of the seed combinations so you can get the Mystery Field Events? You receive any different seeds while playing and fertilizers PLEASE DOES ANYONE KNOW???????PLEASE!!!!!!!!!!!!

This is about Mystery field events, Has anyone got a rainbow seed? Where? How? Did u get a mystery field event from it? If you did what fertitlizer did you use? Does anyone know anyone seed combinations? There are a total of 7 and I have only seen 3, If I am lucky I may get 2 more.
This is what I know:
Crimson Seed + Blossom Branch = Scene
Pink Seed + Sparkling Weeds = Scene
Purple Seed + Sacred Tree Bark = Scene
And I am now trying
Sky Blue Seed + Mystery Soil = ?
Silver Seed + Whale Tail = ?

Does anyone know anything else? If you do PLEASE!! REPLY!!!!!!! HELP ME!!!! It is driving me nuts trying to figure out the last 2 combinations!

I think the last two are scenes too but I'll check just to be sure.

No, just I found out that
Sky Blue Seed + Mystery Soil = ?
Silver Seed + Whale Tail = ?

they don't give you a Mystery field event Now it is getting mad! And I found another Mystery Soil in front of the Kururugi Shrine. And I also read somewhere that you get the Raindow Seed after helping Ishimaru in Minamo Village and then talk to his mother but I did't get it I'll double check, but where I got the Raindow Seed was completely different I was using the girl and hanging out only with Miroku, and after defeating Naraku on Asagiri Island back in Kaede's Village walking passed the field Myouga shows up and asks you if he could suck some of your blood say yes and get a Rainbow Seed. Reply if anbody knows anything.
