You cannot catch Wailord. You can, however, catch Wailmer, which evolve into Wailord starting at level 40.
You can find it in Route 129 but it is rare.
Just train a wailmer to level 40.
Wailord is not available in Firered as are all Hoenn pokemon if you want a Wailord you must trade one from Ruby,Sapphire,or Emerald.
You get wailord in route 129 or evolve your wailmer into a wailord.

Yes, it always has to be Wailord and Relicanth - Relicanth in the first slot and Wailord in the last in Ruby and Sapphire, and Wailord in the first slot and Relicanth in the last in Emerald.
No, u can only catch a wailmer and train it to level 40 and you got a wailord!
Get a Wailmer and evolve it. It evolves into Wailord at level 45.

By catching a Wailmer, train it up to level 40, an it will evolve. In sapphire i think you can catch a wailord.
