I, Zombie Endless

I, Zombie Endless is the tenth and last I, Zombie level. It is the endless level of I, Zombie.

List of possible combinations
Each streak has a possibility to be a certain layout. In all of the following layouts, one to eight Sunflower(s) is/are included (eight plants are Puff-shrooms, being the number of Sunflowers), dependent on the amount of sun you have, as well as your streak. However, the Scaredy Layout has more sunflowers than usual (up to 13) and is also the rarest. The frequency of the Scaredy Layout notably affects how far a player can go.

Other plants in each layout: The Magnet and Fume Layout is the most difficult one, due to the fact that Magnet-shrooms stop the Digger Zombie, Ladder Zombie, Buckethead Zombie, and Football Zombie, until the end and the Fume-shrooms kill Dancing Zombie (and its Backup Dancers) and Imps quickly. Hence, only the Conehead Zombie, Pole Vaulting Zombie, and Bungee Zombie (which are all weak) can be used initially. The player will need to use a lot of sun for this setup.
 * Normal Layout One - one Torchwood, three Spikeweeds, one Threepeater, one Magnet-shroom, one Umbrella Leaf, three Split Peas, three Snow Peas, one Repeater and three Kernel-pults.

Trivia

 * This is the only I, Zombie level that has the Umbrella Leaf, Repeater, and Puff-shroom.
 * The exploding layout is similar to the level ZomBoogie, except that sometimes Sunflower will replaced by Puff-shroom.
 * Although this I, Zombie level is endless, the streak record has a limit of 2,147,483,647 (using Cheat Engine). After that, the streak will be negative but the level will still continue.
