Rain Island Stone
The 
Rain Island Stone allows the player to unlock the 
Aquafall Machine.
After completing the "Rainy Day Delight" quest, the player will be able to use a Rain Island Stone to manually activate the Aquafall Machine once a week by crafting one and placing it into the machine. Activating a weather machine causes the weather event to happen in a random region. A currently active machine cannot be manually activated until the weather event ends. Manually activating a machine during another weather event will end the other weather event even if they occur in different regions.
Crafting
While completing "Island Stone" quest, the player will receive the Rain Island Stone recipe from 
Chococat. In order to craft the Rain Island Stone, you'll need the following items: 100 
Seashell, 50 
Chocolate Coin, and 5 
Spark. The Rain Island Stone can be crafted at Chococat’s crafting bench in 
Seaside Resort.
