Planti-Matter

Planti-Matter can be tapped on to make it shoot a laser, which is guided by your finger.

Overview
When tapped, Planti-Matter will fire a laser similar to the one fired by Laser Bean. Unlike Laser Bean, though, Planti-Matter's laser slowly crawls across the screen and its path can be altered by your finger. For example, if your finger was at the top of the screen and you suddenly swpiped down to the bottom of the screen, the laser would shoot to the bottom lane.

The laser is more accurately described as a pea that changes lanes and leaves a trail, as it's not usually a straight line, unless you don't touch the screen while it's firing. Once the laser reaches the right side of the screen, it fades away. After performing its attack, Planti-Matter will have a 15-second cooldown. Only one Planti-Matter can be firing at a time.

When eaten, Planti-Matter will explode in a 3x3 area, dealing the same damage as a Cherry Bomb.

Planti-Matter is a reference to Anti-Matter.

Plant Food Ability
When Plant Food is used on a Planti-Matter, it will shoot out a laser similar to the big laser shot by Laser Bean, but the player can press on the left or right side of the screen to make it change direction. Eventually, when it either hits its own trail or hits the edge of the lawn, it fades away. This will also happen automatically after a set amount of time.

Strategies
The best place to plant this is at the back of the lawn, as then it can reach the most tiles. Quantity helps quite a bit if you don't have time to wait for 15 seconds after every shot, as then it is possible to fire one after another repeatedly. The sun cost of these are quite high, so you might want to consider planting a lot of sun-producing plants if you are aiming for non-stop lasers.
