Paper Mario 2 help thread

I only have one small question so we might as well make this a general help thread. I have all the shine sprites except for the two in Fahr Outpost and I think one in the Twighlight Trail woods. I am pretty sure it is in the Twighlight Trail woods because when I asked the fortune teller lady she said it was in an eerie woods behind a large rock or something like that. Can anyone give me vary detailed instructions on how to get it. I looked on gamefaqs and they were no help at all.
