What's This?

[Pokemon Trainer1]

I discovered something new in pokemon platinum! I was digging around in the underground, and found a second Odd Keystone! This isn't usually possible, so can someone tell me what this second one does? I don't think it's worth anything, but I think it's a key item

The Secret Keystone should be in your items pocket. You CAN technically get 999 of them, I think. Not that special, you can always breed Spiritomb's anyway.

EDIT: Again, use the Q&A thread...
