The group set the Guiness World Record for the most people blowing a chewing gum bubble simultaneously.

Nintendo's famous pink blob celebrated his 20th anniversary this year, and in honor of Kirby, 536 PAX attendees gathered to do one thing: blow gum bubbles. Together, the group set the Guiness World Record for the most people blowing a chewing gum bubble simultaneously.

"Kirby is no ordinary character, so it's not a surprise that his fans would go to extraordinary lengths to mark his 20th anniversary," said Scott Moffitt, Nintendo of America's executive vice president of Sales & Marketing. "Nintendo is proud to have such a dedicated and enthusiastic following."

The old record of 304 people was set by Kirkwood Community College in Cedar Rapids, Iowa, on October 27th of 2010. In order to beat their record, PAX participants had to chew their gum for at least one minute and blow a sustainable bubble for 30 seconds.

The latest Kirby title, Kirby's Dream Collection: Special Edition, was available for early play on the PAX floor. The game will launch for the Wii on September 16th.
