Frostbite Caves is the 10th world in Plants vs. Zombies 2. It takes place in an ice age. It appears the scene takes place at the Player's House which is a cave that's been outfitted to serve as a home. On the zombie side of the lawn there is a giant cave shaped like a zombie head made of ice, and there are also two mammoth tusks with one of them being broken. The environment modifiers of this world are slider tiles, chilling winds and the surprise attack "Snowstorm!". Slider tiles are ice blocks that float on tiles with water and have a zombie hand frozen inside with its index finger pointing either up or down. This finger determines the lane the zombies that get in contact with it will go towards. (A finger pointing up means the zombie goes to the lane above it. Same mechanic applies to the finger pointing down.) Chilling winds appear randomly during the level, partially freezing plants and they can eventually leave the plant completely encased in a frozen block, which renders the plant useless and also behaves similar to a tombstone. Finally, "Snowstorm!" is a surprise attack which is similar to the "Sandstorm!" surprise attack in Ancient Egypt. Zombies will come directly onto a tile, even behind a slider tile, then continue moving. Zombies that come in by the snowstorms are not affected by the slider tiles. Besides the things mentioned above, there will sometimes be available plants, zombies or both that are frozen in the lawn from the beginning in some levels. The player can release them by using thawing plants, such as Hot Potato. There is also a new Power Up called Power Flame that replaces Power Snow and is exclusive to this world. Themed zombies in Frostbite Caves are immune to freeze. However, they can still be chilled and slowed.
