Minty Leaf is a plant you use to cool down plants. If a Flamethrower Pea or Napalmthrower Pea is getting hot, you can use the Minty Leaf to instantly cool it. It also makes shooting plants shoot their Frozen version of projectiles. Also, if you plant it on an explosive instant kill, the explosive will make a cold version of the explosion. You can also plant it on water to turn it into ice.
