The Halloween Party 2019 was a party and the second Halloween Party in Club Penguin Online. It was hinted at on October 4, 2019 in a brief announcement about the new Penguin Style Catalog. It was also confirmed due to the Furniture and Igloo Catalog showing the party logo and on October 8, 2019 on the What's New? Blog.
It started on October 25, 2019 and ended on November 7, 2019. Alongside the party, HALLOWEEN19 code was released. The custom Green Ghost Puffle was released during the party.
Before the Halloween Party started, puffles begin to feel agitated, and the first three floors of the Puffle Hotel appearing to be haunted. Gariwald VIII goes to investigate the alleged paranormal activity that is happening over there. October 25, the Puffle Hotel shot up thirteen stories overnight, and rumours about Ghost Puffles haunting the Puffle Hotel began to circulate. Gariwald VIII has gone missing while investigating paranormal events there. With the help of Skip the bellhop, penguins have to explore all 13 floors of the haunted hotel, solve puzzles, and assemble the ghost catcher to save Gariwald.
Later, Skip is revealed to be an evil ghost who wants to use the energy of the ghost puffles to haunt Club Penguin Online Island. However, he is defeated by penguins, Gariwald is freed from being kidnapped, and penguins are allowed to adopt a ghost puffle.
