Cattail

its deadly tail poisons zombies

The Cattail is an upgrade for the Lily Pad. It costs $10,000 to buy from Crazy Dave's shop, and 225 sun to upgrade the Lily Pad in the pool. Its tail and name are based on the Typha latifolia, a perrennial herbacous in the genus Typha. Its face, however, is based on the domestic cat.

Suburban Almanac Entry
Cattail 

Cattails can attack at any lane and shoot down Balloon Zombies too.

Must be planted on Lily Pads

"Woof!" says Cattail. "Woof, woof, woof! Does this confuse you? Do you expect me to say "Meow" like a cat just because the word "cat" is in my name and I also look like a cat? That's not how things work around here. I refuse to be pigeonholed."

Cost: 225

Recharge: very slow

Usage
The Cattail has the damage and rate of fire of a Repeater. The Spikes it fires are homing, and can hit zombies anywhere. It attacks zombies closest to the plant, though it prioritizes Balloon Zombies. However, it cannot attack Shield Zombies around their Shields. It is very useful for killing Digger Zombies if they're in the back row, as it will kill them before they can move.

Strategy
Because a single Cattail can cover all six lanes, it makes a good early defensive plant. It also helps deal with Digger Zombies and Imps as well as Balloon Zombies. Unfortunately, all your Cattails will usually fire at the same target (except under certain conditions), and when that target dies, spikes in the air are wasted. This limits the effectiveness of large numbers of Cattails. It is a good idea to use Cattails in limited numbers in Survival Mode.
