There are several tense moments when you are almost spotted -- at one point, a toad steps on Iko's foot, and once, Feng brushes up against one's pebbly skin -- but you make it out of a dangerous situation thanks to Mimi's and Orengi's combined skill!
On the return trip, you keep well away from the haunted valley; you can still feel the tugging on your heartstrings by the faintly heard birdsong.
By late afternoon, you're back at Yao Fei's, where you give the apothecary the deadly mold samples. The slug-man gives you the three doses of antivenom he was able to produce.
What now? To the salt marsh?
