In the North Eastern corner of Opal Bridge there are two thugs beating up a Pachirisu/Zigzagoon. Defeat the look out and then engage the two in a double battle and the Pachirisu/Zigzagoon will join you.
Hiding From The Rain
During rainy or stormy days, a Pansear/Panpour will appear underneath Opal Bridge. Pansear will join without a fight, but not Panpour.
Upon leaving the Grand Hall you find a girl struggling with her disobedient Stufful/Snubbull. She will then leave and go to the apartment in north-western most Peridot Ward.
