Zombies Enemy: Regular Zombie, Conehead Zombie, Ducky Tube Zombie, Dolphin Rider Zombie, Buckethead Zombie, Zomboni, Pole Vaulting Zombie
Recommended Plants: Sunflower, Lily Pad, Wallnut, Tallnut, Spikeweed, Potato Mine, Torchwood, Repeater, Threepeater
This stage gets a little tougher because of the mixture of zombie enemies. Start the stage with standard sunflower production while using potato mine. Start setting up defense early on in the stage by using both Tallnut and wallnut. Stack repeaters with torchwood to take down the zombies.
Setup a few spikeweeds to break down enemy zombonis. Your goal towards the end is to have tallnut in all the lanes to defend against pole vaulting and dolphin rider zombies. Have a couple of threepeaters and repeaters to take advantage of torchwood.
Once you have the defense setup, all the zombies will die quite easily.
