After yu beat the game, go to the Latolato Trail and if you look on your map you can find a river that you can cross with Suicune. Go to the left of the river and you will find an area filled with Gracedia flowers. Normally there would be only Bellosums but instead you will find a Venusaur!
After your Capture Styler is upgraded go to Ranger Signs and while you hold down your stylus draw any sign with the line rainbow colored and there will be a special bonus! If you drew Latias/Latios's sign: He/she will fly faster even when not tapping the screen. If you drew Entei/Suicune/Raikou's sign: all Pokemon you see will be VERY scared of you. Remember there is no bonus when summoning a non legendary, MewTwo, or Celebi.
*works best at canal ruins[/color] First go to the canal ruins Summon suicune Go in the river Go anywhere in the river Dismount suicune but don't go out of the river You should be standing in the water now GOOD LUCK!
