The Great Wall of China - Day 1

 is the first level of The Great Wall of China in Plants vs. Zombies: All Stars.

Difficulty

 * The Primitive Conehead Zombie rarely uses its skill, and will be defeated in two or three hits, so it will not be a big problem.
 * The Slingshot Zombie has low health, but it is a long-ranged attacker, so be careful or you may lose your health. Use defensive plants such as Wall-nut as protection for your plants.
