The Fall Free-for-All Bug Goals event involved catching bugs on Sunburst Island from October 18th to October 23rd, 2019.
Bugs had to be caught by the player, or by using Honey, Flutter Honey, or Beetle Honey to count towards the event goals. Bugs received as gifts from villagers or bought from Market Boxes did not count. After the event ended, any remaining Peacock Butterflys stay in the inventory and are able to be bought, sold, and used to fulfill animals' requests.
