After you're done with Agrabah... you should be able to use the Green Trinity, so, head to Traverse Town and go to Cid's shop. You'll unlock the synthesis shop. Return any pages to the Hundred Aker Wood if you have any. After that, fly to the point east of Agrabah on the map, the lower arm of the new ring, with a Battle LV of five stars. On the way there, you'll run into Monstro. =)
