Skull & Crossbones

Stepping off the boat onto Crescent Island, this is what I saw.
A skull. Bobbing under the gangplank. Boys' faces were a sight!
Later on, walking round the island, we came across these.

Guess every skull must have its crossbones?
But can you picture the boys' faces at this point?!
However, they soon got over their initial shock.
And kept a few for room ornaments.
You've been warned!
