Walkthrough:Kingdom Hearts Re:coded/Darkheart3/Hollow Bastion pt II

Inside Riku's Data
Well isn't this weird. First of all, your inside Riku. Second of all, Riku's inside Riku. Third of all, not only are you and Riku inside Riku, but there's also a Moogle inside Riku, trying to sell you things. O_O. anyway, when you regain control enter the strange door.

Destiny Islands
When you arrive in the Destiny Islands, be on the lookout for little blue orbs. These are your powers. They may be inside Bug Blox, inside enemies, wherever. Keep finding them until the Matrix Power in the top left corner goes up to 20%. When you're done, head over to the little island via the bridge. Proceed through the sector to finish.

Traverse Town
Once you return to the Central Corruption, save and head through the next door. Once again, remember to raise the Matrix Power to 40%. Now, the bugs in Traverse Town have messed up the worlds layout, so don't be surprised when you enter the door to the Third District, and end up in the Second >_<. Follow the path out into the open area, then head through the door to the First District. The sector is located on the door to the Accessory Shop.

Wonderland
Return, save, and enter the new door. Now that it's kind of a tradition, raise the Matrix Power to 60%. Once again, the bugs are messing with this world's layout. Each door will take you to a different place in the Lotus Forest. This time, the sector is located on a Lily Pad, which is located high up on the far end of the forest.

Agrabah
This world is EXTREMELY HARD. You MUST make sure you save. Enter Agrabah, and try not to stray from the path. Warch out for Danger Bugs and Metal Bugs. Avoid them if possible. Raise the Matrix Power to 80%, and get out of the Cave. The sector is located on top of the Guardian's Head.

SAVE

Escape!
You will have to do a Mario style side-scroller. Just follow the path, and ride on moving stone blocks until you escape.
