Silver Pig Coin

SS Companion

The Silver Pig Coin was available through the Recruit-A-Friend program.

This pet was original only available on Chinese servers from December 27, 2007 through January 6, 2008 for the New Year's Celebration. During this period, a limited number of Silver Pigs were available through special activities in-game.

Pet Journal
Druids think silver pigs have a special bond with golden pigs, as both breeds appeared on Azeroth at the same time.
