Well, I'm planning to make a guide about each box item that can be obtained. But it's a looooong way ;)
Honestly I've never got any strange peach personally. I never participate in any event that can reward me with them- I'm simply too weak. So, if you want you can make the guide yourself. Or if you don't want to I can make it ;) Your data- your call ;)
But your data is really usefull. Have you wrote down how many times you got each item? If so, we could calculate approximate chance for each item.

I'm working also on Big Magical Egg item listing, but it goes way slower, because I get it only once a week from Q&A. So far I have.... *drums* TWO ITEMS! xD
Tomorrow I'll create topic about the rest of box items, and what can we get from them.
