As soon as it becomes night, a group of eight fireflies spawn above the third hive. They then fly to a random field and land in a circle, facing the middle. You can nudge a firefly away by walking close to it. If you nudge a firefly away, the flowers where it was sitting will sparkle. When all eight fireflies have flown up, a Moon Charm token, Glitter token (very rare), or a Star Jelly (extremely rare) will appear in the middle of the circle. The fireflies will land in one field three times, after which they will target a new field (if it's still night). They can fly to the Spider Field, Bamboo Field, Strawberry Field, Pineapple Patch, Cactus Field, or the Rose Field. As soon as day arrives, the fireflies will fly away above the hives, and then eventually disappear.
