Royal protection

Spent most of today sorting through boxes that have been in the garage since we moved in, over 15 years ago. I am a bit of a hoarder and came across all sorts of interesting things: old letters, a poem written by a would be suitor when I was at college, my first payslip, some old college essays, and this...
This was given to me when I was age 5 on the cruise ship the Reina Del Mar, by king Neptune himself. I remember being terrified at the time - well, you would be! It has worked though, I have dived with all sorts of things in the past, barracuda, sharks, dolphins, Portuguese man o war jellyfish, and none have tried to harm me. Thanks Neptune :)
