大嘴怪大嘴怪的原型是一只袋獾，首次出现在50年代的动画短片《兔八哥遇上大嘴怪》（Devil May Hare）中，也被称作塔马尼亚大嘴怪，他有着锋利的牙齿和巨大的嘴巴，极度贪吃，几乎什么都吃。转圈时所有东西只要他路过都会吃掉。大嘴怪头部几乎占身体的一大部分，其实个子是很矮小的。在动画里他不会说话，只会：“乌拉哇哇啦啊！”地叫唤。大嘴怪是疯狂的低智商怪物，其运动能力超强，跑起来一阵旋风，称大嘴怪头脑简单四肢发达最合适不过，在动画中，兔八哥经常轻松的整他，他整天被兔八哥搞的稀里糊涂。 [1-2]
Tasmanian Devil; "Taz" for short, is described as: "A strong murderous beast, jaws as powerful as a steel trap, has ravenous appetite, eats tigers, lions, elephants, buffaloes, donkeys, giraffes, octopuses, rhinoceroses, and moose." However, this definition is only partially accurate. He also eats chickens, ducks, and especially rabbits.
Whirring around like a tornado, slicing through trees like a rotary saw,and feasting on an entire ecosystem of jungle creatures, Taz has but one thing on his mind: Eating. The carnivorous native of Tasmania has the power to devour everything and anything in a single gulp. When this furry, salivating beast comes a-runnin', giraffes scurry for their lives, alligators turn themselves into luggage to hide, and sharks literally leap out of the water. And even if you take Taz out of his natural habitat, it is nearly impossible to take away his appetite. Even on Christmas Eve in the suburbs, Taz wants to eat.
大嘴怪像龙卷风一样“呼呼”的旋转，穿过树林，一切都变成了碎片儿了。大嘴怪脑袋里只有一个想法：吃。
