Celestree
Spoilers are on this page.
Players may want to avoid or be cautious toward reading this article/section.
The 
Celestree is a structure located on an island to the northwestern side of 
Cloud Island's 
Critter Corral. To repair the 
Celestree, the player must complete a series of quests that begins with the "Reach for the Stars" quest and ends with the "Constellation Destination" quest.
When repaired, the Celestree introduces a new weather event, 
Starfall. A starfall occurs when the Celestree activates. The player does not have to be nearby. The activation occurs randomly and cannot be influenced by the player. The weather forecast in the player’s menu tablet will show when it is an upcoming weather event. Starfall only happens at 
night and takes the form of a star shower in a random region of Friendship Island.
After completing the "Rainy Day Delight" quest, the player will be able to manually activate the Celestree once a week by crafting a 
Star Island Stone and placing it into the Celestree. 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.
Starfall
Starfall lasts approximately 15 minutes and will only occur during night until 
morning; what appears during the starfall depends on where it is falling.
Star Treasure
Star Treasure will appear during a Starfall only in 
Gemstone Mountain, 
Mount Hothead, 
Seaside Resort, 
Spooky Swamp, 
Cloud Island, or 
Merry Meadow. When opened, each 
Star Treasure will have 3x 
Stardrop inside. There are 5x Star Treasure chests per Starfall period. They do not regenerate with the use of 
Island Bouquets. Even if the player was somewhere else during the starfall event, Star Treasure will stay spawned until the Stardrop is collected or replaced by another Starfall event in the same region!
Stardrops
Stardrops are a type of currency obtained by opening Star Treasure during the starfall. A total of 15 can be collected during a Starfall.
Critters
When a Starfall occurs in Cloud Island, the player will also be able to catch 
Stardrakes around the region.
*Note: Catching the Stardrake requires 
Keroppi's 
"Critter Friend" and 
"Critter Calmer" companion abilities.
Fish
When a Starfall occurs in 
Rainbow Reef, Star Treasure will not appear. Instead, the player will be able to catch 
Starry Snipe, which can be found by fishing above the Kelp Maze or near the 
Comedy Club.
