Caution (The Riddle of Blackbeard's Cove)

Hanging with their girls on the Bayport beach
Frank and Joe Hardy get a call from the chief of police
Their crime-fighting Dad missing on the case
Looking for the pirate with a tattoo on his face
They camp out with Chet through the moonlit night
From across the haunted isle, they spy a flashing light
Meet an old sailor with scabies and lice
Before they stole his boat, he gave these words of advice:
Caution!
We forgot about the boat, so they surfed across the bay
Standing with their guns, on the rocks Fenton lay
Armed only with a shoe and a random sting-ray
Saved their Dad, solved the case, and finished their crouchet
Now the moral of the story is not that crime won’t pay
Cos it’s common knowledge that pirates still exist today
Unlike Frank and Joe, always lucky in the fight
You gotta seek to be prepared for the danger out of sight!
