This is the famous Dancing Zombie [pictured] in Plants vs. Zombies is getting taken out of the game.  The Jackson Estate is against it, and have asked it to be taken out.  Popcap is complying with them. I kind of think this is a little petty, but I have turned off polls that were about me being likened to Mr. Snuffalufagus, so… I can understand.  Of course my friends never let me live down that fact. 

The Estate of Michael Jackson objected to our use of the 'dancing zombie' in PLANTS vs. ZOMBIES based on its view that the zombie too closely resembled Michael Jackson. After receiving this objection, PopCap made a business decision to retire the original 'dancing zombie' and replace it with a different 'dancing zombie' character for future builds of PLANTS vs.ZOMBIES on all platforms. The phase-out and replacement process is underway.
