Tomatank

Tomatank is an offensive plant in PvZ2. It fights with red tomato bombshells that it fires at zombies. It is a Gemium and can be bought for 100 gems, like many others.

Plant Food
Tomatank will suddenly grow up and blast a huge shell down the lane, which will quickly begin running over normal, weak zombies and heavily damaging larger, tougher zombies.

Strategies
Tomatank is a powerful ranged unit that can deal easy splash damage, so plant it at the back of your defense, even behind Sunflowers. It's Plant Food, like Citron's, can be useful for wiping out entire lanes of troublesome Armored zombies, so be sure to use it often.
