Three

3 is a special,explosive plant. When you plant it,it will first sleep. After 5 seconds,the middle 3 will takeof as a rocket,and the others 2-- Wait. When I mean 2,I don't mean "too". And when I said 3,...yeah,I meant tree. After the take-off,another 3 will sleep,while some 1 (NOT SOMEONE) will explode. If the left head explodes,all zombies in a 5x6 area will die. If the right one will explode in a 3x3 area for (Not 4) hypnotising all zombies. The tree rocket? Oh yeah,I almost forgot about that one. After 15 seconds or so [you don't need citation for this] that 3 (AGAIN,NOT ALL 3) wil come to a random square and explode in a 3x3 area. Too (NOT 2,PEOPLE) bad it leaves a crater there,which can't be filled (yeah,I'm looking at you,Fill-in!).

Strategy
Use it when you desire the most,possibly when most zombies arrive. Be careful at its sun cost(which obviously isn't 3),or right in the middle of the battle,your sun cost will be...3?
