ZomBotany

ZomBotany is the first Mini-game, available as soon as the mode is unlocked. It features several Peashooter Zombies and Wall-nut Zombies, which have the same abilities as the corresponding plants. Defensive plants such as Wall-nuts and Tall-nuts are vital here, considering the Peashooter Zombie's ability to damage plants from afar.

Strategy
Most zombies in ZomBotany are somewhat easy to kill; a couple of Peashooters will stop even a Wall-nut Zombie in a minute or two. However, due to the peas being fired at your plants, it is a lot harder to prevent your plants from being eaten. Just put a Wall-nut or Tall-nut in each row (it's a good idea to use the Imitater Wall-nut too) and plant a couple of Peashooters and a Snow Pea in each row and you'll be fine. However, you can also plant a couple of Garlics in rows two and four and a few Gloom-shrooms behind them (three or four per row are enough) and the zombies will be killed without any opportunities to retaliate. Rakes are also a good idea in both setups

Peas from the Peashooter Zombie start coming onto the screen before the zombie itself, which lets you tell where it will arrive.

Trivia

 * ZomBotany is a portmanteau of the words Zombie and Botany, hence, the zombies here are plant-zombie hybrids.
 * It could also be a pun on the word lobotomy which is the act of surgically removing the front lobe of the brain.
 * The Hypno-shroom has disappointingly incomplete effects on plant-zombie hybrids. Although hypnotized Peashooter hybrid zombies do the about face and do munch their normal brethren, they continue to fire peas towards your house (apparently from the back of their head!) which continue to damage your plants. They also are not harmed by peas fired by normal peashooter zombies and so don't run interference for your plants.
 * Zombotany was orginally going to have its own music.
