Machine Gum

Machine Gum is the [number pending] plant unlocked in [world pending, can be requested to be added]. Machine Gums rapidly shoot weak seeds, some of which have sap on them.

Suburban Almanac Entry
Sure, Machine Gum has his faults. He's impatient, quick to anger, and sometimes just plain insensitive. But you gotta admire his work ethic.

Plant Food
Tilts back, then fires a huge sappy seed that does 1 nds to and slows every zombie on the screen.

Implementation
Machine Gum will shoot seeds much faster than the Peashooter and other shooting plants, but at the cost of projectile damage. However, it does more DPS than other shooting plants (2 damage/second).

Strategies
Machine Gums can be useful when used correctly. If beginning-game sun is not an issue, it might be wise to purchase a Machine Gum and place it close to the back of the lawn. Due to its recharge, it is advised not to use this plant as fodder.

Due to the small chance of slowing zombies, using it against fast zombies is not entirely advised. However, its DPS makes it useful on weak zombies with (or without) additional slowing. Its slowing sap means its slowing effect is the same as Sap-fling's, and cannot be stacked with it. This may be inconvenient in some strategies that involve Sap-flings, however it may actually be more useful than before.
