at sand gem city
After capturing Giratina, go talk to prof. Rowan in Sand Gem Town.
Lvl 20 its moves are sand tomb, take down, sandstorm and dragon rage =D
sand gem
There is no legendary sand Pokemon. you must of got confused with fake Pokemon and real Pokemon
You catch Hippowdon at Route 228 where the sand is and you catch hipportas at route 224 in the ruin maniac cave which evolves to Hippowdon at lv34
All u have to do is get the national dex and then go down from sand gem town and when the rocks split go to the right then just keep going then you'll end up at the migratting zone
After getting pokedex compleeted go to sand gem talk to proffeser rowan he will give you national dex and pokeradar keep in mind have to beat poke leuage
The Burmy's cloak depends on where you last used it in battle. A plant cloak in grass, sand cloak in caves or beaches and a trash cloak in buildings.
first you have to get giratina then fly to sand gem town talk to the professor then you can go to sunny shore city hope i helped bye
When you go to sunyshore city to battle the last gym leader after you beat him you have to go get the move waterfall from jasmine who is the girl on the sand. Then you use surf on the water behind her which is route 233.
if you mean vanish as in flee like mesprit, cresselia, moltres zapdos and articuno, its because they are supposed to do that and they do that in platinum and diamond too. you can only get moltres zapdos and articuno in platinum. to stop them from fleeing, you should have masterballs or a TRAPINCH in your first slot but you cant switch out because it knows sand trap or whatever its called to stop Pokemon from fleeing or have a haunter or any ghost Pokemon that knows mean look or a sudowoodo that knows block and USE those moves IMMEDIATELY when you see them. hope i helped! :)
