User blog:MignightHawk/Somebody Explain this?

Okay, the following pic is a very odd Zombie death. Things I'd like to point out:


 * 1) This was a Regular Zombie on the PS Vita version of the game.


 * 1) His entire mouth area is swelled up.


 * 1) His head stayed on as he died.


 * 1) He did not Bite any Garlic. Only a Tall-nut.


 * 1) This has happened more than once.
 * 2) The PS Vita was acting fine at the moment.

Can you explain this? I sure can't.
