Fignite

Fignite is a plant in Plants vs. Zombies 2. If a zombie is at least 5 tiles in front of it, it will lob fireballs that do 1.5 NDS and leave zombies with a burn effect. This burn effect will damage them more overtime for 5 seconds, dealing 9 NDS total. It will lob again once the burn effect is over.

Fignite will get angry if a plant is destroyed, 1 or more zombies above 70 health enter the lawn, or if the player loses a lawnmower. When one of these events occur, Fignite's damage will be increased by 1. When it gets angry for the third time, it will explode in a 3x3 area, dealing 30 NDS and leaving zombies with a burn effect.
