Nintendo will continue its celebration of Kirby's 20th Anniversary next month when it attempts to break a world record. The platform holder will gather as many people as it can at PAX Prime on September 1 for its Guinness World Records attempt for the most people blowing a chewing gum bubble simultaneously.The current record is 304, and participants will also get the chance to win prizes, including Kirby's Dream Collection: Special Edition, which launches in US on September 16. Kirby's Dream Collection Special Edition is a celebratory release packing six games spanning from Kirby's Game Boy roots right up to Nintendo 64. It'll also feature a load of bonus challenge stages based on last year's Kirby's Return to Dream Land, soundtrack CDs and a timeline database of Kirby's history.
