This fun poem by Lewis Caroll catches at the imagination, with its crocodile on the nile. It's from Alice in Wonderland

How doth the little crocodile
Improve his shining tail,
And pour the waters of the Nile
On every golden scale!

How cheerfully he seems to grin,
How neatly spreads his claws,
And welcomes little fishes in
With gently smiling jaws!
