This is the first version that Popcap did, before Michael Jackson died. One of the zombies looked like Jackson from his Thriller video. Jackson's family asked popcap to remove the zombie from their game as a mark of respect. I think enough time has gone by now though and much prefer the Jackson dancing zombie to the replacement popcap used.
