Aquafall Machine
Spoilers are on this page.
Players may want to avoid or be cautious toward reading this article/section.
The 
Aquafall Machine, also called the Aquafaller, is a structure located to the right of the Kelp Maze 
fast-travel point, in the northeast side of 
Rainbow Reef, next to the Dune Lagoon.
The player will unlock the Aquafall Machine while completing the "Rain or Shine" quest. After completing the quest, the player will unlock weather on the island, where it can be either 
raining or 
sunny! The Aquafall Machine will occasionally activate, making bubbles as it causes rain to fall somewhere around Friendship Island. The player does not need to be near the machine for it to activate. The weather forecast in the player’s menu tablet will show when it is an upcoming weather event.
After completing the "Rainy Day Delight" quest, the player will be able to manually activate the Aquafall Machine once a week by crafting a 
Rain Island Stone and placing it into the Aquafall 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.
Rain
Rain lasts 15 minutes, and what appears during the rain depends on where it rains.
Rainfall Flowers
Rainfall Flowers will appear during rain only in the 
Seaside Resort, 
Spooky Swamp, or 
Merry Meadow. When watered using the 
Watering Can, they will produce 
Raindrops. There are 15 flowers per rain period. They do not regenerate with the use of 
Island Bouquets. Even if the player was somewhere else during the rainfall event, the Rainfall Flowers will stay spawned until the Raindrop is collected or replaced by another rainfall event in the same region!
Raindrops
Raindrops are a type of currency obtained from watering Rainfall Flowers during the rain. A total of 15 can be collected during a rainfall.
Critters
When a rainfall occurs in 
Gemstone Mountain, Rainfall Flowers will not appear. Instead, the player will be able to catch 
Soaking Sluglers around the region.
Fish
When a rainfall occurs in 
Mount Hothead, Rainfall Flowers will not appear. Instead, the player will be able to catch 
Shower Springtail, which can be found in the Hot Springs and along the coast.
Rainbow Beams
To obtain 
Rainbow Beams, the player must complete the "Rainbow or Bust" quest. When a rainfall occurs in 
City Town, a total of 3x Rainbow Beams will spawn in random locations around the city. Rainbow Beams will stay spawned until they are collected or until it rains in City Town again. Additionally, the player can find 3x Rainbow Beams after reset each day following the completion of the "Rainbow or Bust" quest.
