All people know that fish can’t growl
Or yowl, or hoot, or hum, or howl.
They cannot squeak, they cannot squeal,
They cannot bark just like a seal.
They cannot purr, nor can they cluck,
With whistling they are out of luck.
They cannot hiss just like a snake.
But there’s one sound all fish can make.
There’s someone who can solve the riddle.
His back is bumpy like a griddle.
But that’s, beware, no easy task,
A crocodile you’ll have to ask.
