Wall-Nuts need a buff.

Wall-Nuts cost 75 Sun, (it should be 50 Sun) and Wall-Nuts are not that strong, basic zombies take them out quick, and as a Wall-Nut fan I am sadden by this. So, if you can, it would be nice for you to make Wall-Nut stronger. Please and thank you.

P.S: Still believe Puff Shroom should be a tier 1 plant.
