There are not many complex Strategies to Wall-nut, as his purpose of blocking zombies is rather simple.
A common strategy is to use a Scrapper plant and place a Wall-nut in front for protection. This protects the Scrapper plant and allows it to deal damage in close-quarters while also being safe. Though all in all, Wall-nut behind any plant gives the same result, providing protection.
Wall-nut's Plant Food, Shell Shove, is simple and effective. It pushes zombies back, and also stuns them. This is effective for slowing down the horde, or if a zombie gets too far down the lane and needs to be pushed back.
Wall-nut's Tacobility is Jugger-Nut, providing a tough metal shell of armor. This gives Wall-nut extra health, but due to being Armor, this can also protect him from a strong attack that would usually defeat Wall-nut, giving him, in a way, two lives.
