Kai Piranha

This card game from Oliver Igelhaut has fish feeding on fish. The cards show different types of fish in different sizes, from hungry to full. Players draw cards and play them to rows, with hungry fish eating everything in front of it until it meets a similar fish. A fish doesn't eat its like, and instead goes to the table as a fat fish. When a player has drawn 3 cards of a kind, he can take a fat fish from the table. When the round ends, players score for the most fish in their catch.
