Saving Leaf Valley
There are three ways to save the Valley from Funland's construction:
Follow event path 1, and pay Alice 50,000G at the end of year 2
Complete at least 3 "Nature Preserve" events
Complete at least 3 "Tourist Spot" events
While the first event path is the one dealing with Alice and the 50000G, the other 15 event paths are either Nature Preserve or Tourist Spot events. You can see them divided into their categories below:
