Pokémon Emerald Tips

Obtain a Castform
Okay, I think this pokemon is very extra rare.

1. Go to route 119, go northwards, until you find the weather laboratorium, go inside, there is many Team aqua members in there.
2. Beat all of the team aqua.
3. After you beat all aqua team, don't exit this laboratorium...
4. Talk to the professor, this professor is in the West, so you have to careful to see. Talk to him and he is very thankful you saved him so he will give you a castform... ^^
