The island Quests are a series of islands that you can travel to to face new enemies. You can travel to islands by going through the Ship Maps 1-2 & Zepplin Maps 1-4. They recently added 2 new islands, Pharaohs Isle & Elven Isle. In order for you to continue to the next island, you must beat the current one your on with 1 star to get to the next one.

There are silhoutted islands which hint that there may be more islands made in the future.
The silhoutted islands look like the outline to Mythical Isle.
The islands are called 'isles' instead.
You can see Octopusses in the water just like on Mythical Isle.
