Summary, in this quest you just need collect Refreashing Leaf, Green Furball and Bristly Beard. So far I have collected Refreashing Leaf and Green Furball. Both of them were drop in Abou Forest with any difficult. Anyone know where to get the last one Bristly Beard?

You can get it from Ganbuki's.

They are located in Kishinden

Nice! Thank you very much XD
