Iceburg Lettuce

Iceberg Lettuce is the first LOT plant in the game.

It costs no sun and freezes every zombie that steps on it, dying after it freezes the zombie.

Unlike PvZ2, Iceberg Lettuce freezes multiple zombies on the same tile on it.

Iceberg Lettuce cannot freeze every zombie in the game though, this includes:

Zomboni, Yeti Zombie, Ice Block Zombie, Yeti Imp, Arctic Trooper, Balloon Zombie, Pogo Zombie, Bungee Zombie, Aerobics Instructor, Ballerina Zombie.  Gargantuars  are affected by ice, but the affect doesn't last as long.

Iceberg Lettuce can be found on Page 1, Seed 10, having a ''' limit of 3. '''

They are based on their appearance in Plants Vs. Zombies 2, almost functioning identically to how they do in the game.
