Thursday King EarthWormie Day is a short event in Cookie Run where the players will be rewarded with a prize just for playing once in a specific day.

List of OccurrencesEdit

  • Every Thursday 4-25 June 2015 (Reward: 1 Supreme Treasure Chest Ticket)


  • It is the first event to be named after an obstacle and an object from Treasure Merchant.
  • The Japanese name of the event is 木曜日イモムシちゃんデー. イモムシ means caterpillar rather than earthworm. The ~ちゃん (chan) suffix is used for familiar language, such as when the speaker finds a person endearing -- it has no direct English equivalent but the translators have chosen to make the name sound "cuter" by using "wormie" rather than worm.
