Fireflies

Fireflies are passive mobs that only appear during Nighttime. Individually, they produce sparkles on the flowers that they land on. Fireflies band together to generate various items for the player.

As soon as Nighttime begins, a group of eight fireflies will spawn above the Star Hall. These fireflies will then fly to a random fields. Fireflies can fly to the Spider Field, Bamboo Field, Strawberry Field, Pineapple Patch, Cactus Field, or the Rose Field. Once they reach the designated field, they will land randomly in a circle, facing towards the center. Fireflies also spawn Sparkles on the current flower they are on.

The player can chase a firefly from its position by walking close to it, forcing it to fly up. They will fly up if a player is within a 3-flower radius. If a firefly is nudged away, the flower the firefly sat on will generate sparkles. When all eight fireflies are nudged away and fly up, the following might appear in the middle of the firefly formation:

Possible Drops	Rarity
Moon Charms	Common, increments of 1, 5, 10
Glitter	Rare
Star Jelly	Very Rare
Night Bell	Extremely Rare
Star Treat	1/1,000,000
Waxing Crescent Moon Sticker	Rare
Glowing Smile Sticker	Extremely Rare
Star Signs	Extremely Rare
Cyan Star Sticker	Exceptionally Rare
Shining Star Sticker	Exceptionally Rare

The fireflies will continue this cycle in one field three times, and afterward, will target a new field. This cycle repeats until daytime arrives. When daytime arrives, they will fly back above the Star Hall and eventually despawn.

Trivia

• The face of a firefly has the same face as the Gummy Bee, but the color of the face is black and not cyan.
• Fireflies, Frogs, Chicks, Hostage Chicks, Spotted Chicks, and Bean Bugs are the only passive mobs in the game.
  • Fireflies were the first passive mob introduced to the game.
  • Fireflies are also the only passive mobs to spawn exclusively at night.
• If a player uses a Night Bell when a group of fireflies are leaving, another group will replace them. In an unknown update, the old group will come back instead of a new one.
• Despite the fact there are eight fireflies, the Glowing Smile Sticker only shows seven "fireflies".
