You talk to the dude at pokemon center at that profesor dude's lab's townand he will ask you for some words.
The first one say ''everyone'' and ''happy''
Then the next set say ''giratina pokemon''
Then go to the 5th gym beat it if you haven't already beaten it then go north and walk into the tall grass
Giratina should attack
Be careful It can run away so get a pokemon knowing mean look
