Snow Bells

Snow Bell is a premium plant in Plants vs. Zombies 2. He is tied to Iced Stream.

Snow Bell lobs ice balls. An ice ball does 40 dps to a single target and once it hits a target, it leaves a snow pile on that tile. The snow pile will slow down any ground zombie that happens to walk over it and disappears once 5 zombies walk over it.

Snow piles do not stack. Only one snow pile can exist on a tile. For example, if a snow pile can withstand 2 more zombies and an ice ball hits a zombie on that tile already with that snow pile, the new snow pile will replace the older snow pile. Snow pile also won't form on irregular surfaces like water or on tiles with plants.

Origins
Snow Bell is based on Heuchera, commonly known as alumroot or coral bells. The plants in this genus are evergreen, meaning they don't lose their foliage during winter or dry season.

Strategies
Snow Bell should not be used as your main offensive plant as his damage is relatively light compared to the cost. His main role is to be a plant that inflict slow effect to zombies, so pair him with strong offensive plants.

Plant Food Effect
Snow Bell when fed with Plant Food will hurl ice balls to all zombies on the screen.

Winter-mint Effect
When boosted with Winter-mint, Snow Bell's ice balls will now make 3x3 snow pile on impact.
