I whipped this thing out in ten minuets, let's see how long before I retcon it. Though, the Fruit Islands do seem pretty tasty.
(I tried to keep all the places from ending in "Kingdom". If there wasn't a good word I could think of, I created one myself. So, you have the Cittàbbia (Città + sabbia = sand city), cittuoco (Città + fuoco = fire city), and giungla (which is just jungle).)
