Is there any way to get the zombie farm app on an android phone?

[bearbear32]

I have the MyTouch 4G, so I know my phone's quality could support the zombie farm app...but where do I get it? I haven't rooted my android because I don't feel the need to, but I would seriously do it just to install this game and un-root my phone...
I know there is a way to do it. Lol. Please help.
