Head over the the Market store in Pet Society, in the section labeled "Cool Stuff", and you can find a World Cup Specials set of sports goods, such as soccer uniforms, a Soccer Goal, and a Bouncy Soccer Ball for just 2,800 Coins.
Sold separately, the goal post and ball are both 1,000 Coins each. We're lucky the game hasn't decided to make these items premium. I'm glad to report that the Bouncy Soccer Ball is really super bouncy! Try setting it in your pet's room and it's sure to hop and roll away from you. Unfortunately, you can't use it to play ball with your pet. But Pet Society does have a bouncing ball game which provides you with a free ball! See how I dressed up my pet, Peachy Keen, in Referee's Hat, Black Soccer Cleats, White Soccer Shorts, and Referee's Jersey. Even Hideeni came by to watch us play!
And speaking of Hideeni, his mission this time is to visit everyone's homes to give away 15 flags of countries participating in the game. You can expect all this fun to be available until July 12th, which is basically one day after the end of the 2010 FIFA World Cup.
