-A true rarity, only one of these elephpants exists in the wild. It was designed by OpenGoodies to celebrate PHP's 20th anniversary on June 8, 2015. After developing the prototype the project was canceled because final production would not be ready in time. The single prototype was put up for auction on [Ebay](http://www.ebay.com/itm/2015-golden-elePHPant-PHP-039-s-20th-birthday-1995-to-2015-/321776947704) on the day of the anniversary.
