Keep doing missions until there is a comotion in the square where they talk about how Alakazam's team hasn't come back from fighing Groudon. Then they pick these random three Pokemon from different rescue teams and they go. Then you keep doing missions then there will be another comotion in the square. It'll be about the random team and how they couldn't get to Groudon. Then your rescue team get's to try to go fight Groudon.

Hope this helped.

One day 2 Pokemon will come too you and tell you they have a mission for you. Go to the bulitin board then take the mission that says "punish bad mankey" and you will talk too the 2 Pokemon again. You will gain access to uproar forest. Go too the dungeon and when you reach the 9th floor walk around until you get a crestnut and recruit an aipom or take a Pokemon with the ability pick up and make sure before you reach floor 9 take the item your Pokemon with pick up has and on the 9th floor take their item. Next go to the 10th floor and beat the mankeys. When you finish the mission you will get a cresnut and the mankey gang will show up. They will see you have a peeled cresnut and ask you for it. Once you give it to them your partner will ask the mankey's to help rebuild your team base. Then after it is a little rebuild the mankey gang will ask for a cresnut to work so give them the cresnut and they will work some more. Then give them another cresnut and the team base will be compleated. Finally the next morning there will be another earthquake and your partner will take you to the square.
