Icy Holly

Icy Hollies are instant-use, plant-modifying plants that turn the plant's projectiles into frozen ones.

Overview
When one uses an Icy Holly on a plant, that plant then shoots chilled versions of its projectiles. These new bullets now slow down zombies. This does not modify damage in any way.

It cannot be used on Melon-pult, any plant that does not fire projectiles, or any plants that already fire chilled projectiles..

It is based off of the ilex genus, otherwise known as hollies.

Strategies
Use Icy Hollies on plants that shoot strong or fast projectiles. Plants such as Laser Bean or Cactus are also recommended, as they can fire through multiple zombies.

A chilled Pea-nut can cause zombies to eat it at a slower rate, keeping it alive longer to deal more damage.

Try to avoid using it on Banana Launcher if you already have Missile Toe. Also avoid plating it on slow-firing plants, such as Coconut Cannon or Citron, as they'll most likely take out the zombie they hit, which renders the slowing addition moot. It is not recommended to be used on Peashooter, as the overall cost will be more than a Snow Pea
