Pokémon Diamond and Pearl/Amity Square

Amity Square

At the northeast and northwest ends of Hearthome City there are entrances to Amity Square, the place where you can take a cute Pokémon for a stroll. These Pokémon are Pikachu, Clefairy, Psyduck, Happiny, Buneary, Pachirisu, and Drifloon.

It is definitely worth visiting this place, as you will find many valuable items here along the way.
