Little John hates porridge.
He hates obeying his elders.
But naughty John finds himself hurtin' for certain when malicious sea marauders kidnap him and bring him to their pirate ship.
John, quick on the uptake, soon understands that no one can help him.
To leave the ship, you and John must collect keys to unlock and collect the ship's holdings. (Luckily, the pirates are confirmed drunkards.)
Pressed for time, you and John must dodge wild birds, vile rats and blood-thirsty pirate guards.
Escape to other floors, or risk starting over!
Remember, your number of lives is limited. No time to hesitate! Good luck!
