In Pokémon Diamond, Wishmur cannot be found in the wild, as it is not a part of the regional Pokédex for the Sinnoh region. Instead, you can obtain Wishmur by trading with players who have Pokémon from other regions, such as Pokémon Ruby or Sapphire, where Wishmur can be found in the wild. Alternatively, you can also trade for it through online platforms or Pokémon forums.
