Cactus: Standard spikes, Aspearagus spears, which pierce through multiple Zombies, and homing spikes, similar to the standard ones but they home in on Zombies similarly to Cattail Spikes.

Sunflower: Sun machine-gun (or whatever it's called), Sun burst which explodes, doing heavy damage to groups, and a Sun laser that cuts through an infinite amount of Zombies.

Chomper: Maybe as well as it's standard biting, it could have a shotgun-style weapon where it shoots teeth?
