Frostbite Caves - Day 4 is the fourth level of Frostbite Caves in Plants vs. Zombies 2. The Hunter Zombie makes his first appearance here. In addition, there are two ice floes, with one being on the fifth column and fifth lane pointing up and the other being on the seventh column and fourth lane, pointing down. When this level is finished for the first time, the player gets a Mystery Gift Box.
Even though the Hunter Zombie is introduced here, he does not pose a big threat.
Hot Potatoes are great for unfreezing any plants that Hunter Zombies manage to encase in ice. Also, thawing plants will also help, such as Pepper-pult .
As with previous levels, zombies come in large groups. Defensive plants are the best way to pass the level smoothly, with Wall-nuts being more than enough to slow down zombies.
The unusual placement of the slider tiles is ideal for the zombies. The fourth row is certainly the most vulnerable one. To avoid any sudden scenarios, defensive plants in the fifth row are great to slow the zombies' advancement.
The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.
