Don't have a Zombie Man: Zombie Simpsons

I play lame little games on my tablet everyday and one that I keep up with is The Simpsons: Tapped Out. I grew up with watching them, quoting Bart, and even through out my life someone can always bring something back to this ever running show.
The Simpsons is one show that does a really great job at Halloween episodes. Treehouse Horror has even showcased an episode with zombies in 1992 named "Dial Z for Zombies". Man I was in kindergarten then! This show is old! So it is no wonder DeviantArt danosborne has created some wicked zombie Simpson art. 
I am digging the detailed hairiness of Otto here to the left. Feel Otto just kinda is a zombie with him being all mellow most of the time.
