so i am in route 32 (in johto) and there is a pokeball on the floor that says its wrapped i should leave it. after looking at the forums i seen you talk to esna and solve to issue. however after talking to her she just sings and i still cant open the pokeball. is there another requirement to the pokeball or am i missing something? thanks.
