Artichoking

Artichoking is a plant that chokes zombies in a one-tile ahead and one tile-behind radius.

Info & Strategy
when the first zombie walks up to it, it grabs that zombie and holds it in one of it's tendrils. it repeats this for the next two zombies that come, and when all three of it's tendrils have zombies in them, it begins choking the zombies. eventually the zombies die, but at different times for different-strength zombies. if it finishes choking one zombie but not the other two, it can use it's third tendril normally, and pick up another zombie. however, it is vulnerable when all three tendrils are full, so it would be a good idea to put it behind a wallnut or tallnut(or inside a pumpkin or something). it is also vulnerable to vehicle zombies and gargantuars, for obvious reasons.
