Cactus

The Cactus is a combative, projectile based plant that acts as the primary defense against Balloon Zombies.

The Cactus could be inspired by any number of members of the genus Cactaceae, but it most resembles a Saguaro Cactus, albeit with a red flower instead of a white one.

Powers
The Cactus' main power is to shot spikes at zombies in air or on the groud.

The Cactus' plant food upgrade is to keep shooting lots of spikes at the zombies.

Trivia

 * The Cactus, the Cattail, and the Sea-shroom are the only projectile-shooting plants having a projectile which has a color not similar to the plant's color.
