> 
> 
> […] 
> 
> 
> A sherbet, or milk, or water  
> 
>  Anything may fall, it absorbs them all  
> 
>  How much water does it drink?!  
> 
>  It gulps down whatever you give  
> 
>  Be it from a jug or a bucket  
> 
>  Amazingly, its stomach never fills  
> 
>  I have heard that **it can even hide a river inside!**  
> 
>  The earth knows how to do magic! 
> 
>
