Halloween 2017 (also known as Halloween Party 2017 or Haunted Halloween) was an event in Club Penguin Island that began on October 18, 2017 and ended on November 1, 2017. It was first confirmed in a blog post on the Island News Blog on October 7, 2017. During the event, players had to team up with Gary to defeat ghosts that are haunting the new Island Central, and collect enough ghost energy to charge his invention, the Deco-nator 3000, and use its vacuum mode to rid of the ghosts. After the ghosts were defeated, all players could receive prizes from the limited edition Halloween shop.
