Frostbite Falls was the eighth map stage in Plants vs. Zombies Adventures. It introduced the Ice Block Zombie to the player. It seemed to be a large ice floe at the bottom of multiple frozen waterfalls. After completing Level 25, the player received the Deputy Badge, which was used to reclaim The Police Station Lot.
Its name was a portmanteau of "frostbite," a condition where skin is damaged due to freezing, and "falls," a shortening for waterfalls. The name may have been a reference to the show named The Rocky and Bullwinkle Show, which featured Rocket J. Squirrel and Bullwinkle Moose as the main characters, as the show's location is in Frostbite Falls, Minnesota.
It appeared to be an ice mass floating over the bottom of multiple frozen waterfalls. There were multiple zombies frozen in the waterfalls, and multiple penguins. There was a radio station and a plow at the side, so there may have been even more snow before.
Frostbite Falls contains 25 stages.
