See something horrible bobbing in the water? Does it stink?
Well, you might have floaters!
Floaters are that special brand of zombie that for one reason or another have ended up in the water, either having drowned or been knocked off a boat, whatever. Once in the water though, they pose much less of a threat. Despite what you might have heard, it’s hard to walk on the bottom of a lake or other body of water without weights to keep you from moving around uncontrollably as the water currents move around you. Plus a person’s natural buoyancy makes it even harder. Sure zombies don’t have much air in their lungs but there are plenty of gasses all through their bodies to keep them from walking smoothly along the bottom. Zombies are also notoriously uncoordinated which gets even worse in the water.
The most dangerous types of floaters are those that make it to shore where they can stand up again and threaten people on shore. At that point they would be more of the “dripper” type. Any that have clothes on are going to be less of a threat but as those clothes get tugged off by the water they’ll be lighter and a bit more mobile, so look out for those skinny dippers!
