“A Wanamingo's just the single orneriest critter there is. Tall as two men, stronger than a bull brahmin, and with flappin' suckers instead of arms. Can't be hurt with guns, neither. S'posedly, injuns called 'em up for revenge on the white-man for what the war did. I don't put much stock in that, though.”— Marge LeBarge about the Wanamingo
牠們是一結古怪的變種生物，喜欢居住在地下洞穴里。Despite the rumors of their extraterrestrial origin, 牠們是FEV病毒實驗的產物，被設計來用於和他國進行戰爭的武器，後來牠們脫離束縛而自由。In that aspect, they are similar to deathclaws.
In Fallout 2, they are called "wanamingos" only in Redding and "aliens" elsewhere, but eventually, "wanamingo" came to be used for the species as a whole across the wastes.
瓦纳明球的身体占整体体型的大部分，一个充满剃刀般锋利牙齿的大嘴，还有一对长长的触手似的附肢，似乎是被用来抓住物体，或是打击敌人。该生物的巨大头部同时也是身体，缺乏可见的感知器官，似乎不需要视力来定位猎物。与任何其他形式的陆地生物几乎没有相似之处。The creatures are devastating in close combat, chewing at foes and lashing at them with their tentacles. Through a process not entirely understood, these attacks also induce radiation poisoning.
瓦纳明球的群体中，由女王— a large grey-colored wanamingo which others fearlessly protect来负责生育，瓦那明球并不具备高智力，但是它们之间有一种蜂巢思维。
Wanamingos are fierce foes and a potent threat to lower-level players. They are highly resistant to most damage types and can hurl a flurry of powerful attacks at their enemies in close combat. However, they have a natural weakness to fire and will flee if one of their feet becomes crippled.
Wanamingos are strange mutant animals that live mostly in underground colonies. They are often mistaken for extraterrestrial beings, due to their otherworldly anatomy. They can easily shrug off damage which would tear the flesh from the bone of a human, and are truly a force to be reckoned with.

瓦那明球的首领， found in the depths of the mine in Redding.唯一已知的一只女王于2241年被获选者杀死。具有繁殖能力，and can be found deep underground in her breeding room.
When targeting any form of wanamingo, the option to shoot an area labelled "the eyes?" appears. It is clear to see that the wanamingo doesn't have eyes, thus, when hit in said area, the player receives the dialogue "Wanamingo was hit in the eyes? for 'X' hit points, damaging its air (?) intake."
Wanamingos appear only in Fallout 2. Mutant wanamingos do not appear in the files of Fallout 3, but can be found in the book The Art of Fallout 3, an art book available with the Collector's Edition of the game. This book also includes a new version of wanamingo mutated by radiation.
