Fluffy

"Daddy, what are you doing with Fluffy?"

Fluffy has a very brief mention in the Nazi Zombie game mode. Fluffy the dog had belonged to Samantha, the daughter of Dr. Maxis and is mentioned in Der Riese by two of the radios. One radio broadcast hears Dr. Maxis giving Fluffy to Samantha. He tells her that she is pregnant and is expecting puppies soon, Samantha asks if she can keep one, Dr. Maxis says that it will be taken "one step at a time." The plan seems to fall to pieces soon afterwards, as Fluffy is secretly killed (unknown to Samantha) in an experiment by Edward Richtofen and Maxis. The experiment was to have dogs the same as the human zombies. But the fatal time is when Samantha walks in to the lab to see her father, Edward leaves the room, locking her and Maxis inside, with Fluffy, who is now a Hellhound. And because Fluffy was pregnant with puppies, she gave birth to Hellhounds, thus creating more and so on. Shortly following this, the Der Riese facility was overrun by zombies and hellhounds. It is unknown what became of Fluffy following her giving birth, or whether she has the ability to teleport like her children.

Trivia

 * There is a bloody paw print between teleporter Z-C and the cave area in Der Riese that could possibly belong to Fluffy
 * There is also a possibility that Fluffy is a German Shepard. If you teleport (in Kino Der Toten), turn to the right you will see a picture of a German Shepherd with notes wrote on it. This could be Fluffy.
 * Fluffy is the only identified Hellhound.
