Blue-alert Berry

"What's this? A plant has gotten the hold of one of my recent creations, and is freezing plants to their advantage? WHAT!?"

- Zomboss's reaction to Blue-alert Berry

Blue-alert berry is an airborne plant that first appears on (TBA), and in the level (TBA).

This plant has two roles:
 * 1) Freezing the zombie closest to the house every 10 seconds by shooting at it with a laser
 * 2) Converting nearby plants within a 3 by 3 radius into their frozen counterparts.
 * 3) For example, Peashooters turn into Snow peas, and Chompers into Yeti Chompers. Any plant that doesn't have a frozen variant will instead have an ice effect to their attacks.
 * 4) If this plant were to get removed by any means, all plants that were under it's influence will revert to their original forms.

Strategies
As this plant mostly buffs nearby plants by adding an ice effect to their attacks, it can be treated in a similar way to Moonflower by putting it in an area surrounded by plants, and as such, is reccomended to be used in the middle of a huge wave.

It's freezing buff takes about 5 seconds to deploy, and it's freeze ray takes 10 seconds, making it slow for a supporter. As such, it's reccomend to have at least two of them.

However, it's ice boost doesn't work on Fire plants, which means that it cannot boost any plant. Therefore, it's best used when a fire plant isn't planted or planned to be planted, as it will negate the buff when within range of it.

It's Freezing attack is meant to stall any zombies close to entering the house. This can be taken advantage of, as this can take out fires and stop the toughest and fastest of zombies in their tracks. The only downside is it's attack speed, which means not every zombie will be frozen.

The plant food ability is best saved for when a zombie is about two tiles away from the house, in which can save the player from losing the level. The disadvantage to this is that it has to recharge for as long the laser was fired.

Trivia

 * The almanac joke is a reference to a Spongebob scene. Specifically, a scene in SB-129.
 * When planted next to another Blue-alert berry, they get a boost on their freeze duration.

Origins
The Blue-alert berry is based off of the Blueberry, which is a small berry that is often grown on bushes.

It is also based off of the UFO, which is a floating veicle that is often depicted as a saucer, and the Freeze-ray, a weapon that freezes anything it fires at.
