In addition to the numerous items that can be fished up (on the hook, in a sea monster, from roaming pirates or in a sunken chest) the oceans now yield more adventure.
As of today . . if a Fisherman hauls up a 'Sunken Treasure Chest' from an S.O.S. (M.I.B.) there is a 30% chance it will contain a Token for entry into Poseidon's Realm.
If you obtain a Token for Poseidon's Realm you can save it, trade it, sell it or use it. By DBL Clicking on the Token you will get a message Gump offering you the chance to proceed with the adventure or wait for another time. If you proceed you will be given a book of instructions saying where to search for the entrance to Poseidon's Realm. When you arrive the way will be opened for you (and your friends if you like) and it will remain open for 10 minutes. The entrance and the realm itself is a no Mark, no Gate area so get your friends on a boat with you if a group is your plan.
Poseidon's realm is not a place for the weak of heart but the creatures there along with an assortment of Treasure chests (lying on the bottom) could make the venture worth while.
