Dangerous scent

Exploration Stage: Autumn Valley
From: Lady Peacock
Description: The professor asked me to find him a "sunflower tiller" to recharge his "explorer." That quirky machine not only plows the fields, it also makes them smell like flowers. Look for the "valley." The Sunflower Tiller should be there somewhere.
Completed: Have you found it already? There are many dangerous flowers in my hometown. But the fragrance of the flowers produced by this "sunflower cultivator" is a hundred times more dangerous than those!
