What's more creepy to me isn't there look but why there called "Drowned Zombies". Is there back story a scary death of drowning causing there bodies to full up with water, and they also got caught in some fishing net that might be choking them. The only thing making them feel less in pain is there clueless personalities.
Personally, I love them! I've probably seen grimmer- and to me they're just harmless blobs that require just a couple shots or less to take down. XD My sisters aren't such fans of them- but they have to get used to the zombie thing, and they can only be lucky Dead Mike (one of my crewmates- Sierra and Austin got Gaspard and Birgus) is a normal zombie. XD
