What powers do lightning reed, grave buster, and coconut cannon have?
These are the attacks and powers of each of the plants you have mentioned above:
Normal attack: Lightning Reeds fire electricity at the closest enemy within 3 lanes of where it is planted similar to the Threepeater. The electricity will also arc to another enemy if close enough.
Plant Food Upgrade: The Lightning Reeds plant food upgrade is that it will generate a small storm cloud that chases zombies, dealing massive damage and will then move onto another target and do the same.
Normal Use: Grave Busters consume graves they're planted on. Usage: single use, must be planted on graves.
Plant Food Upgrade: -None-
Normal attack: Its usage involves tapping on it where it releases a cannonball (coconut) in a straight line in front of it where it will explode when it hits the first zombie doing splash damage (3x3 area). A direct hit from the Coconut Cannon deals approximately 45 normal damage shots. It then requires a cooldown period of 16 seconds.
Plant Food Upgrade: The Coconut Cannons plant food upgrade allows it to release a gigantic coconut, pushing all zombies to the right of the screen doing incredible damage as well as killing each zombie in a 3x3 area at the end. Can still be used during cooldown, but will start it if not.
