Ghosts and ghost hunters have taken over Disney’s Club Penguin, the #1 virtual world for kids, in its annual Halloween Party. With over 6 million penguins taking part in last year’s event, Club Penguin’s Halloween Party is the biggest Halloween event online for kids. The fun and fright continues in this year’s event, where players will need to solve the mystery of ghost-researcher Gariwald VIII’s disappearance and uncover the secrets behind his Walt Disney Parks and Resorts-inspired haunted mansion.
