Plants vs zombies wall nuts

Wall nuts are plants which provide protection for your plants. It is first protection plant that you get after beating level 4 of pvz, and they cost 50 sun. Unlike other plants, they take a whole heck longer to be eaten. So always put them in front. The wall nuts are better than nothing but it is a huge problem since in case you have a chomper half way chewing. There is a wall nut first aid which can be bought in the shop for 2000 coins, and that heals any protection plants other like tall nuts, and pumpkins. Oh and one real cool thing in no 2 game they are more protected if you put plant food on them!!!!!!
