Caribbean Treasure is a Z-machine interactive fiction game written with Inform 6 and is © 2025 by Garry Francis. This game is an adaptation of the 1987 Italian adventure Alan Simmons: Bucaneer by Bonaventura Di Bello. See credits for more details.
In this island adventure, you play as Alan Simmons, a young man who loves sailing and pirate stories. In an old manuscript, you learned about a sunken pirate ship near a then-uncharted Caribbean island which you found on modern maps. Intent on finding pirate treasure, you sailed a rental yacht to the island and started exploring. Unfortunately for you, your first discovery is some footprints on the beach heading to your yacht and back!
This solution is by David Welbourn, and is based on Release 1 of the game.

This is the response to XYZZY, PLUGH, PLOVER, or YOHO:
The ghost of a drunken pirate appears singing,
"Fifteen men on the dead man's chest.
Yo-ho-ho, and a bottle of rum!
Drink and the devil had done for the rest.
Yo-ho-ho, and a bottle of rum!"He then fades away. How strange...
