How does Pokemon Emerald catch the dragon of the sky?
Go to the director of the Institute of Meteorology after customs clearance, and he will say "the weather on XX Road (or waterway) is abnormal". Go where he said. If it is land (sunny), you should find a cave. When you enter the innermost part, you will see Gulaton. When you walk in front of him, you can start. If it is an ocean (rainy weather), find a diving area of about 4 square meters. After diving, you will see the innermost Hague, and you can start playing when you walk in front of him.
Remember, there is only one master ball, and it's best to catch black dragon.
Seafood teeth are best caught with food stall balls or challenge balls.
Gulaton had better use Daima's ball and play with him for 30 rounds before catching it.
Remember to file before you catch it! If you make a mistake, you can read this file.
