go into the gym
There in the gym in mossdeep city by the way the gym leader are actually gym leaders.
To get to Mossdeep City, you have to defeat the other six Gym Leaders, and you need Surf. In Mossdeep, there is a Psychic-type Gym, and Team Magma will be in the Rocket place.
No, you can't go to the moon to get Jirachi at all in Pokémon Ruby, Sapphire or Emerald, not even after defeating the Mossdeep Gym Leaders.
It is on Mossdeep City. There are Twin Gym leaders
The sixth gym is Mossdeep City Gym - Gym Leaders Liza and Tate (Mind Badge). You have to surf right of Lilycove city.
Yes, but they fight as 1 team: double battle.
After you beat the 7th gym leaders talk to steven in mossdeep city.
defeat the mossdeep city gym leaders and you will receive it after their defeat.
the people give you hints to find gym leaders.
You will see them again at the Cave of Origin. There is a cavern that you will need to find underwater to get to the Cave of Origin. You will need to defeat the Mossdeep gym leaders.
It could be anywhere between Mossdeep and Lilycove. The dark sea parts can be dived into but you need HM08, which is dive. Get it from Steven in Mossdeep (he's in the house at the top-left corner of Mossdeep). Just talk to him and he will give it to you. But you need to defeat the Mossdeep Gym to use dive. The Gym leaders use Psychic/Rock type Pokemon. You need a Dark or Water type Pokemon to have an advantage against them. P.S. Believe me, I had a Wailord in level 40 and I still had difficulty defeating the Gym leaders. Remember, the Gym leaders are twins so they use two Pokemon at the same time. SO put your strongest Pokemon at the top of your Pokemon list. Good Luck!
