Mermaid had a problem. A terrible, horrible, smelly, problem. The Terrible Horrible Smelly Pirate is back! And after discovering a secret treasure in Halifax Harbour, he's not so smelly anymore -- but Mermaid's island is. The poor misty island is covered in people's garbage! Just when it seems all is lost, she spots a rickety rackety pirate ship through the salt spray -- and a not-so-terrible, horrible, smelly pirate and his crew! What if she could trick them into cleaning up her Terrible Horrible Smelly Beach?
