Painsettia

Painsettias are instant-use, poisonous flower plants that infect a large area of zombies ahead of them.

Overview
Painsettia is an instant-use plant. When plated, she releases a large toxic cloud in a 4x5 area in front of her (4 tiles ahead in every row). This infects every zombie in the area with poison. The poison acts similarly to Shadow-shroom's poison, as it corrodes through armor, but now it does 2 damage points per second.

The toxic cloud Painsettia creates lingers for 2 seconds. During this time, the player can plant a Blover or Hurrikale to affect the cloud. Blovers will push the cloud forward 2 tiles, while Hurrikales with only affect their row, but push the cloud throughout the entire lane.

Painsettia is based off of the Euphorbia pulcherrima, more commonly known as poinsettias. Its exaggerated poisonous nature is based off of the fact that poinsettias are mildly toxic, with consumption causing vomiting or diarrhea, but nothing harmful.

Strategies
Painsettias are best utilizes when planted near large groups of zombies, as they are then able to infect many of them. However, they shouldn't be planted too close, as then the toxic cloud will go off the lawn, where it does nothing.

Its high sun cost and slow recharge are also something to consider. Because of these qualities, Painsettia should be planted wisely and tactically.

Trivia

 * As mentioned previously, actual poinsettias are not highly toxic, and Painsettia's nature is highly exaggerated compared to its real-life counterpart.
