The Japanese famously love to eat raw fish and one of the very best kinds of sashimi or sushi is tuna (maguro). The realistic 3D Tuna Dissection Puzzle by Megahouse is a fun game with 33 pieces that also teaches you the basics of fish science. Take apart this large tuna delicacy and then put it back together. The puzzle also features a board and fake knife, so you can pretend to be a sushi chef preparing your fish dishes for diners.
