Someone please help

So I'm working on my own take on a Plants Vs. Zombies game, and I'm liking the promise of it so far. One hiccup. In order to prevent myself from having over 100 different Plant and Zombie sprites I condensed them to one, with each getting their own animation and lines of logic. The side effect to this was now whenever I want to make whatever plant was placed look like it was actually placed all the instances change their animation. I know why this is, but surely there's a way around it, right?

Then I asked the silly AI to fix it for me to which I was offered the same solution twice before I figured I was missing something and opted to let it sort it out. I looked back and it deleted all of my other code and didn't fix the issue. Just thought that was a little funny.
