게 울다

cry like that; (animals) make their sound

-게 supplies the manner and 울다 the crying. The catch for learners is that Korean uses 울다 for the noise an animal makes, not just for weeping — three of these lines are about animals: 고양이는 야옹 이렇게 울잖아요 'cats go meow like this', 너구리는 어떻게 우나? 'what sound does a raccoon make?', 돼지가 꿀꿀 이렇게 울기 때문에 'because pigs go oink'. The rest are people crying, usually with 이렇게 or 그렇게 marking how hard.
