ZomBotany is a portmanteau of the words "zombie" and "botany," since the zombies in the mini-game are plant-zombie hybrids.
Hypno-shroom has incomplete effects on ZomBotany zombies. Although hypnotized Peashooter Zombies appear hypnotized and attack other zombies, they continue to fire peas towards the player's house from the back of their heads, which continue to damage the player's plants. They also are not harmed by peas fired by normal Peashooter Zombies and so do not run interference for the player's plants. These bugs have yet to be fixed, except for the iOS version, where hypnotized Jalapeno Zombies will still destroy the player's plants.
In ZomBotany, most plants can take 16 peas worth of damage before being destroyed. Garlic also takes the same 16 peas, as it also takes the same amount of basketballs from a Catapult Zombie as a normal plant.
ZomBotany in the iPod Touch version is worth $10,000. It is also the only mini-game on the iPod Touch version that is not available in a game pack.
