Frost Rose

Frost Rose is the Rare ice variant of Rose. Like all the other ice-based characters, Frost Rose sacrifices some of its damage in exchange for a freezing ability. Once an enemy is hit by Frost Rose, they will become chilled, causing them to suffer from a slight movement speed penalty and to gain a blue, frosty visual overlay. If Frost Rose hits a target multiple times in a quick succession, it will freeze the enemy solid, fully immobilizing them and preventing them from using any abilities. Frost Rose's primary weapon is also semi-auto compared to other the other Rose variants. It was revealed in a live PopCap stream, where it is revealed that it can charge up attacks like the Future Cactus.

Stickerbook description
"Frost Rose once rode a majestic Yeti Chomper into battle. The resulting victory was so convincing that the mere whisper of it makes Zombies shake in their boots."

In-game description
''Hold down fire to charge her icy shots. The longer you charge, the quicker your enemies will freeze!''
