Fear The Walking Dead
In Episode 2.03 "Ouroboros" Nick comes in contact with Mr. Crabby. Not only is Mr. Crabby the most disgusting infected that we have encountered with Fear The Walking Dead, he is the one that Nick learns that Infected guts camouflage you from infected attacks.
Mr. Crabby is played by Joe Giles who is a special effects technician on The Walking Dead and Fear The Walking Dead.
If Mr. Crabby looked familiar, that is because he has played two walkers on The Walking Dead.
