Oogie's Manor is a Disney boss original to the Kingdom Hearts series. After Oogie Boogie is defeated for the first time in Kingdom Hearts, he fuses with his manor to create a giant boss. In order to defeat it, the seven Shadow Globs possessing it must be destroyed.
This is one of the few boss battles where Sora can enter and exit the arena at will, the others being the Opposite Armor battle and the Captain Hook battle. There are two possible exits; one on the Bridge, and one at the creek on the left side, once Sora jumps down.
If possible, travel to and lock the Keyhole in Neverland before beginning this fight to learn the shared ability Glide; using this ability makes it easier to reach the shadow globs covering the manor. Glide also comes in handy to keep Sora from falling to the ground and forcing him to climb back up, which can be time-consuming.
When traveling on the manor, always be ready to use Guard because there are swinging objects that may push Sora off. No matter where Sora is located, Oogie always looks around and finds a chance to attack, and it may be difficult to see the globs in the darkness of Halloween Town, so be prudent. To avoid overlooking the globs, constantly use Lock-On to find the nearest target. When attacking the globs, watch out for the two lanterns swinging around, as they will throw balls of fire at Sora. The lanterns can be destroyed for more experience points; dodge the flames until it swings over the platform that Sora is on, then either hit it a few times or use Blizzard magic, but try not to fall off the platform. Also try summoning Dumbo (if available).
Oogie has five offensive techniques in this form. The large lantern that he has at the start will produce tongues of flame to damage Sora's party, and if destroyed, the smaller, spider-shaped one nearby will light up and begin shooting fire instead. Oogie can also blow poisonous dark spores from his mouth, which will cause continuous damage for several seconds. If Sora lingers too long where the lanterns were, Oogie's arm will slam down in an attempt to hit him. Finally, after destroying a few of the dark globs, Gargoyles will start appearing, which will continue to spawn until the battle ends.
