 * Defeat Heartless and collect hearts!

Story summary
Roxas arrives at his new destination as Jack Skellington is still attempting to improve upon Halloween. Roxas also runs across the demented trio of Lock, Shock, and Barrel. Roxas's departure in turn inspires Jack's next Halloween spectacular!

Afterward, Axel returns from his second Castle Oblivion mission and meets up with Roxas. While speculating on Xion's whereabouts, she sits in her room, upset over an encounter on her latest mission.

Mission walkthrough
Ah, at last, another new world. Halloween Town should, as usual, look extremely familiar to those who played the original Kingdom Hearts, down to the world layout. You'll enter the appropriately named Halloween Town Entrance and fight off some minor Heartless on your way to the Square. Upon arriving, more Heartless are hidden around the square, most notably near the entrance of the Graveyard, the southwestern corner, the northwestern corner, and on the stairs to Jack's House in the northern alcove.

Once you have found these Heartless, go into the Graveyard, where you will be greeted by five Hover Ghosts. Destroying three of them will fulfill the regular mission, while taking out all of them completes the optional goal as well. Whatever your choice, the ability to RTC will be opened, so take out as many as you like, and then head back to the Entrance to RTC. Mission complete!

Challenge Mission
Shouldn't be too hard if you have abilities equipped to help move around fast. Stock up on Fire to easily defeat Skater Bombs (as long as you are far enough away to avoid getting caught in the blast and getting frozen) and Hover Ghosts while using regular attacks against the Creepworms while ignoring the rest.
