Curious Children Song

Here is a children's song that you may have heard of. "The Animal Fair"

I went to the animal fair,
The birds and the beasts were there,
The big baboon by the light of the moon
Was combing his auburn hair,
The monkey bumped the skunk,
And sat on the elephant's trunk;
The elephant sneezed and fell to his knees,
And that was the end of the monk,
|: The monk, the monk, the monk. :|

I am sorry, is there a monk visiting the animal fair (but why?), and then an elephant sneezed, fell on his knees and crushed him?

Why does children song has lyrics like this?
