在阿帕拉契亚中2103年有三种元素浮體蟲，通常以群体形式遇到，并经常与超级变种人一起被发现，他们双方友好，把对方当作伙伴，并攻击动物。Floater flamers glow red, have incendiary abilities, and have vertical pupils. Floater freezers glow blue, have cryogenic abilities, and horizontal pupils. Floater gnashers glow green, have pupils in the form of a plus sign, and have acidic abilities.
↑Joshua Sawyer: "I think Floaters are cool critters in the Fallout universe, but, like Centaurs, they have really weird bodies that require unique animation rigs. From an animation perspective, limbless flying things tend to be really cheap (usually), human-like bipeds are cheap, quadrupeds aren’t too bad. Once you start getting into creatures with multiple heads, snake bodies, tentacles, etc., they get really expensive. IIRC, we talked about having Floaters but we just didn’t have the animation time for them." (Joshua Sawyer on Tumblr)
