Cattail

The Cattail is an upgrade for the Lily Pad. It costs $10,000 to buy from Crazy Dave's shop, and 225 sun on the lawn (plus the 25 sun from the lily pad).

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.

Usage
The Cattail has the damage and rate of fire of a Repeater. The spikes it fires are homing, and can hit zombies anywhere (except underwater). It attacks zombies closest to the plant, though it prioritizes Balloon Zombies, and it can attack Shield Zombies around their Shields.

Strategy
Because it can cover all six lanes, it makes a good early defensive plant. It also helps deal with Digger Zombies (it can shoot backward) 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.

Almanac entry
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!"

Trivia

 * Cattail is the only upgrade water plant.
 * A Cattail can be downgraded to a Lily Pad if you have a Pumpkin on it and try to dig up the Cattail, which could be useful on a Pool or Fog Survival Level without the Lily Pad chosen.
 * It is a dog with a cat hat.
