This stage is long and combines more zombies from previous stages. Just follow the format and setup in 3-3 and you can beat the stage in no time. However, this time you get a new plant, the kelp which acts as a cheap way to kill water zombies instantly.
Setup the 6~7 sunflowers like usual, and start building out your center lanes. If you are a little bit slow, you can use kelp to take care of center lane beginning waves. However, you usually don’t need it.
Once you pass the stage, spend the gold on Twin Sunflowers first.
