find a wailmer then evolve it
The Pokemon Mansion is home to some rare Pokemon. To find it in Pokemon Pearl version, go to route 212.
I think you can find them in the Pearl Version of Pokemon. Since I have the Diamond version of Pokemon I had to trade a Pokemon (wireless) to obtain a glameow.
you can only find that pokemnon in pearl version sorry
any sea
You must trade one from pokemon pearl/platinum version
The easiest way is to use the Poke'Radar.
Wailord is an immense Water type Pokemon. It can be encountered in the wild in Pokemon Sapphire while Surfing on Route 129.
