Tractor Bean

Tractor Beans are lane-diverting, offensive plants that bring random zombies in front of them to attack.

Overview
When planted, Tractor Bean targets 5 random tiles with zombies on it. It then pulls every zombie on those tiles in front of it. It will then charge down its lane, dealing 40 damage points to every zombie it hits. It will stop after it moves 7 tiles and attack again -- if it hasn't already gone off screen.

While Tractor Bean's locating system is mostly random, Tractor Bean will target some zombies more than others. For instance, zombies closer to the house are more likely to be targeted. Special tiles, such as Gold Tiles or water tiles, with zombies on them are also more likely to be targeted.

Zombies in front of a close-ranged attacking plant or a defensive plant are less likely to be targeted. Tractor Bean will never target a zombie that has already been diverted by a plant (such as Garlic or Sweet Potato).

Tractor Bean's design is based off of the kidney bean. Its name is a portmanteau of "tractor beam," a beam of energy that is able to bring objects inwards, and "bean."

Plant Food Ability
While the window of time where Plant Food can be used on Tractor Bean is short, it is possible. Doing so causes Tractor Bean to bring in every zombie in the lanes below, above, and on it. It then charges forward dealing 65 damage points. This, however, causes the Tractor Bean to roll off screen, no matter how tiles it traveled.

Strategies
There are two ways to utilize Tractor Bean's abilities.

Tractor Bean can be placed far away from the house, where it can virtually bring zombies back to the front of the lawn, as well as hurting them. This way, if Tractor Bean doesn't take out the zombies it hits, the zombies are a good way away from the house. However, Tractor Bean will charge off of the screen on its first attack.

Tractor Bean can also be placed closer to the house. While stronger zombies that were targeted may now be closer to their goal, Tractor Bean now also attacks twice, giving you more uses out of a sluggish-recharge plant.
