KINGDOM HEARTS HD 2.8 Final Chapter Prologue

In the world map use the drop menu, Y button, to see the forecast for the world you'll be visiting. if there is an outline of a dream eater on the left that means the special portal for that dream eater has appeared. The name of it will show underneath the three day forecast. Once you complete the portal, the dream eater will show up as completed in the drop menu. There are some worlds were there are multiple versions of the same dream eater but in different portals. Refer to your game records to see which portals you have done so far, so you arent running around looking for the right area. Also if you can seem to get the right special portal for a specific character just continue to drop between characters until you get it to show up.
