Lobster

The type of lobster I am basing this on is the European Lobster it would have an adult and baby version and the player can breed them with kelp. Lobsters would also live around the stony shores biome and could go on land but for only a short period of time something like one or two Minecraft days. Lobsters will not attack the player but they will if the player attacks them when killed lobsters will drop the lobster claw which is a new food source able to fill 4 hunger points.
