Dialogue[]

(Crazy Dave and Penny appear)
Penny: W-w-warning, User Dave! I am r-r-running l-l-low on antifreeze!
Penny: If my systems f-f-f-freeze up, we could be stuck here forever!
Crazy Dave: It'll be a cold day in heck before I let that happen, Penny!
Crazy Dave: Time to unleash Fire Peashooter!
Crazy Dave: She can apply heat to those zombies, and warm up nearby pals too!
(Crazy Dave and Penny leave)

Difficulty[]

The player should not have much trouble with this level, as plenty of Fire Peashooters and Snapdragons are given in the level to easily warm plants up caused by freezing winds. The only dangerous zombies present are Hunter Zombie and Blockhead Zombie.

Snapdragons and Magnet-shrooms are advised to be placed behind the slider tiles or the Wall-nuts once frozen, so they cannot be attacked.

Spikerocks are difficult to use if placed far to the right as many freezing winds come around and freeze them. Since Fire Peashooter would almost be bitten instantly if planted to the right, most Spikerocks will stay frozen for the rest of the level, unless they were placed in proximity to Snapdragons. .

Strategies[]

Created by Rifqitheflipper
  • Unfreeze the Wall-nuts to block early zombies.
  • Plant Fire Peashooters behind the Wall-nuts. Do not plant them on row 2 or 4 yet until at least three peashooters are placed behind the Wall-nuts.
  • Plant Snapdragons behind the slider tiles and Magnet-shroom directly behind it.
  • Plant Spikerocks in front of the Wall-nuts, mainly on the center row.
  • Spend Plant Food on either Snapdragons or Fire Peashooters to deal with Blockhead zombies.
