Once upon a time, 

A little mermaid lived

in a deep blue sea.

But soon things came adrift...

Suddenly the sea wasn't so blue,

It had taken on an ugly hue.

The little mermaid was sick.

Up she swam. 

Wrong move. 

Caught in a net.

Sent to the zoo.

"Money Maker Mermaid" 

was her new name. 

If you litter, be ashamed.
