Paradise Falls is the World of UP. Despite its name, Paradise Falls is in fact the world with the highest number of Heartless and Unversed, but has the lowest number of Nobodies. Harley and Ares are the only ones present when they end UP (get it?) in this odd world. The ally here is Kevin (that bird, remember?), and for defeating Charles Muntz (the other old guy who was after the bird), you get the summon "Doug and Russel" (the dog and the kid).
