Yes, they have used that tactic of using zombie guts. I was talking about putting the "different" walker in the mix. It came up because someone upthread noticed a strange walker amongst the "washed-out white" walkers on the bridge. All the walkers were white from being buried in the sand. The skin, hair, clothes etc. were all white. Then in the middle of those walkers was a "normal" walker. A lady with bright colored clothing. I would never have caught it if someone on here did not mention it. It looked like a blooper. But the more i keep hearing about the new group, the Whisperers, it has been speculated that maybe this was one of them, or a foreshadowing of this new group. Most did not catch this. Could be nothing, could be a blooper, could be whisperer. They are always putting "easter egg" type things in the show, so many are now on the lookout.
