Blueberry Pachinko

Blueberry Pachinko is a plant that once planted, will bounce on the row it is planted. It will move to the right until it hits the end of the right screen. After that, it will bounce backwards ( to the left) and will bounce to the right again when it reaches the house. It repeats this. When it meets a zombie, it will squash the zombie dealing 8 normal damage shots. It bounces with the speed of an imp. The maximum number of Blueberry Pachinkos planted at a time is 3. When a Blueberry Pachinko meets another blueberry pachinko, they will bounce off each other and bounce backwards.
