Pirate's Treasure

The Pirate's Treasure is a quest.

Start
Talk to Redbeard Frank at Port Sarim and he will tell you about his old captain who buried treasure somewhere. He is willing to help you find it but he wants some Karamja Rum before hewill tell you where it can be found.

Obtaining the Rum
You are informed that the rum is sold at a bar on Karamja and will cost around 30 coins, plus you must be able to get the rum back to the port without it getting seen by the sailors.

Travel to Karamja, go to the bar and buy yourself a rum, but do not leave the island just yet!

You will need to think up a plan in order to get your rum off the island as you can neither take the ship home or teleport without risking the removal of it. Go talk to Luthas, an NPC located in a hut near the boarding platform, who tells you about the customs officer, ask him also for a job, which he gladly gives. He wants you to fill up crates each with 10 Bananas outside his store. There is a banana plantation just near this on which you can quickly pick 10 bananas and take them back to the shop. Place the rum then the bananas in the crate. Talk to Lutus and he will give you 30 coins, now you can travel back to Port Sarim.

Arr, matey
Head over to the Gerrant's Fishy Business in Port Sarim and get an Apron hanging on the wall and then head for the Wydin's Food Store. Put it on and head into the storage room where a man will stop you. Ask him for a job here, he will agree and now you can enter. Search crates until you find the rum then head back to Redbeard and give him the rum.

Whilst he drinks he gives you a key and says it unlocks a cupboard In the Moonlight Inn in Varrock. Head over there and go upstairs, search all the cupboards until you find a parchment. It tells you the treasure is in Falador's park where x marks the spot.

Treasure
Have a search around the Park until you find an x marked in dirt spots. Dig with your spade and you will be attacked by a level 4 farmer, kill him and dig again to complete the quest and get you treasure!
