Update: LEGO moves quick as it seems Superspeelgoed already 404’d the images.
Dutch site Superspeelgoed spilled the beans on LEGO Minifigures Series 4 by posting the image above. This is quite possibly the best series yet not because of the werewolf bone, nor the geisha girl head that looks like an Amidala head, nor the awesome garden gnome, nor the ice skate element, nor the mohawk, nor the new bottle element with the mad scienteist, no, none of those reasons. The main reason why series 4 rocks so much? It includes my sigfig head on the skater.
Image are linked directly from the Superspeelgoed site. LEGO will probably ask them to take it down so grab the images while you can.
Thanks to ccjwprongs for the heads up.
