There is now an image, courtesy of The Brick Fan, of three more characters from the LEGO Collectible Minifigures Series 12. The picture comes from the new LEGO Club Magazine and it shows the Prospector, Spooky Girl, and the Piggy Guy.
The Prospector carries a pickaxe, the Spooky Girl has a teddy bear, and the Piggy Guy has an apple.
