I, Zombie Too

I, Zombie Too is the second I, Zombie level. The zombies avaible are Zombie,Buckethead Zombie and Screen Door Zombie. The plants in the level are Peashooter, Sunflower, Snow Pea and Spikeweed

Strategy
As Screen Door Zombie 's screen door is resistant to the Snow Pea 's freezing effect,it's best to use them in the rows with Snow Peas, but be aware that Spikeweed can damage the Screen Door Zombie even if he has his screen door, so don't use him in the rows with multiple Spikeweeds because you would waste 100 sun. There may be row with two Snow Peas, but in these rows there are no Spikeweeds, so put a Screen Door Zombie in these rows.

Use Buckethead Zombies in the rows where there are Spikeweeds and Snow Peas,as a normal zombie wouldn't survive in that row. Remember that, and you are good to go.
