This is the third visit walkthrough for Traverse Town as it is featured in Kingdom Hearts, as well as its Final Mix version. After finding a Navi-G Pieces in Neverland, Donald suggested they return to Traverse Town, with Sora adding that Cid would install them.
Walkthrough[]
Upon returning to Traverse Town go and talk to Cid, after which you can access the next location; Hollow Bastion (walkthrough). Before leaving, visit the Item Workshop and synthesize any new equipment if possible. It should be kept in mind that after events in Hollow Bastion every single world's Heartless will drastically change, gaining attributes on par with level 50 on average. As such, acquiring items used for synthesis, or other activities on said places, will be far more difficult compared to the current low-level enemies.
If you have not yet, you can collect the Spellbinder from Merlin and the Wishing Star from Geppetto. You should also use this opportunity to clear the Hercules Cup and visit all the worlds for any missed items, as Goofy suggests when you leave Traverse Town.
