"It does not seem like this would be the case, but the bloat can form from any person, not just fat people. The bloats body is mainly swelling skin as well as muscle and is not all fat, however it does like to eat seemingly infinitely and its preferences are not limited to meat, in fact these zombies have been caught eating french fries, chicken, or anything edible they can find. They are slightly smarter than normal zombies and unlike other zombies the bloat can heal (a trait shared by the puppet). Also unlike other zombies it fully digests its food and apparently produces no excrement. The bloat can take many bullets before it even realizes that it is hurt, and this is due to its immense swelling more than anything else. The bloat can be slower than the normal zombie or it can be faster depending on how strong it was as a person.
As an added side note bloats are stronger than regular zombies and upon an attack they will bite and tear viciously. They also have what appears to be a severe case of eczema but show no signs of knowing or caring."
The audio wasn't really that challenging to make, but that makes sense because its not really all that great. Still fun to make though.
