u should make it to the hideout in veilstone and a grunt will be there so talk 2 him then looker will show up with the key 4 the warehouse
You go to acuity lake
Because you're not using Platinum. -hope this helps
He went to the lake near twinleaf and you have to fight team galactic
You do pretty much nothing except battle team Galactic. You do learn though that team galactic is trying to capture the Pokemon of all three lakes. This is when you travel to lake acuity.
get to lake acuity the first time and the team galactic members will stop you so then go to the snow point city gym leader and battle her and defeat her and the team galactic grunts will go away. then go inside and you will see your rival helping galactic boss Jupiter out of the water and will know the he is a fool to help Jupiter and will go away crying. after this you are allowed to go to to sunny shore city.
It is found at Lake Acuity. If you defeated it, it won't appear. Also, I think it appears after you defeat Team Galactic at Veilstone City.
After helping your rival at Lake Acuity, your next step is to complete the gym in Snowpoint City. If you've already completed the gym and have the Icicle Badge, your next step is to make it to Veilstone City to deal with Team Galactic's HQ.
After the player defeats Gym Leader Candace at the Snowpoint City Gym, the player should return to Lake Acuity. There they will discover that their rival has lost to Commander Jupiter.
you have to go to lake acuity near snowpoint city after defeating team galactic for good and having battled giratina. surf across the lake, enter the cave and as you speak to it you will battle it.
Team Galactic will be in Lake Valor after you win the Canalave City Gym Badge.
there are no team galactic grunts in that game. only team rocket, and they are not at lake of rage.
try battling them..
