Coral Island Episode 4

The game teaches me why there's an entire sub-panel in the Crafting menu for scarecrows.
I start completing Errand tasks for extra cash.
The Pufferfish story expands, as I learn that the town has reached an "F" rating ever since an oil spill affected the nearby ocean waters.
I actually make it into the Cavern.
And I have a mysterious vision. Dream? From a voice that wants to save the island.
