Hippopotamus in Your Pocket

When you have a hippopotamus in your pocket,
You may feel that you can do anything,
If you wish it, well then, who can block it,
With a hippopotamus to do your bidding?

But please consider the feeling of that hippo,
Who trusted you enough to ride along.
You are the responsible one in this duo,
And it’s up to you to tell right from wrong.

So, have a pleasant adventure with your buddy,
And be home again when it is suppertime.
We would like it if you don’t get too muddy,
And please don’t the two of you commit a crime.
