Pokémon Diamond and Pearl/Floaroma Town

Sonoo Town is the town of Flowers. Thus being so, there is a berry shop in town that will exchange Accessories (for the Pokemon contests) for a certain amount of a certain berry. Also, in the 'foresty' part of town, a guy will sell you Sweet Honey for ¥300.

The route next to it will be closed until you defeat Mars in the Windmill Facility near by. On Fridays, a Drifloon will appear. This is the ONLY time you can catch one, as it's not found anywhere else in the game. If you accidentally KO it, it won't appear again until the next week. Also, it won't appear until you defeat Commander Mars.
