Kingdom Hearts 3D: Dream Drop Distance/The Grid

Dive Boss: Brawlamari
During his dive to the Grid, Sora encounters the enormous octopus Nightmare, Brawlamari. It can attack by either shooting lasers from its tentacles, splitting a boulder, slashing with its tentacles, shooting spheres of light in place of ink, or slowing its fall in an attempt to get Sora to collide with it mid-dive. All attacks can be dodged with, excluding the last; press for Sora to perform an aerial brake, momentarily slowing his fall and avoiding a clash with the Nightmare. Following this attack, Sora will be close enough to Brawlamari to be able to attack. Target the colorful bubbles on its head until it once again speeds up its fall, restarting the barrage of attacks which Sora must dodge. Defeat Brawlamari quickly for a high rank. The less health Sora loses, the quicker the battle.

Main
When Sora drops into the world, he recognizes it from his previous visit despite the visual changes. Upon gaining control, make the necessary preparations at the Save Point and Moogle Shop before jumping in. Update your Command Deck to accommodate the stronger enemies, upgrade the Keyblade from Skull Noise to Guardian Bell, spend some time with your Spirits, and create new Spirits using the recipes from the Moogle Shop and exploration. Now, progress forward to meet the new Nightmares. Clear the area, then find the red tracks which lead to the next level. Before taking them, use Flowmotion to get up on the ledge behind them. Here you should find a chest containing Troubling Fancy. Now drop back down and hop on the tracks; Sora will use Flowmotion to take them up. Defeat the next set of Dream Eaters and take the red track to the right. Sora will have to jump off mid-ride to catch a chest on a ledge to his right. Open it for a Water Barrel and continue up. Once you reach the top, defeat the Dream Eaters that spawn and find the tracks leading down to the left. Again, take the right track and hop on a right ledge for a Block-it Chocolate 2. From here, head down the stairs to the exit.

Use the tracks to help dispatch the Dream Eaters in this area quickly. From the entrance, turn right around the corner and use Flowmotion to get up this wall. Here you will find a large chest containing Circle Raid. Now ride the track up ahead for a scene. Sora gets into trouble with the local guards, and he must now fight them. Before moving forward, turn around and drop down to find a chest containing Confetti Candy. Now jump back up and follow the path to trigger an attack by the guards. These aren't typical Dream Eaters; they're tough opponents, complete with strong combos and aerial attacks. Use the tracks extensively to deal plenty of damage without taking much yourself. Following their defeat, climb up the tower next to the path here using Flowmotion to find a platform at the top by some tracks. Open the chest on it for a Dulcet Figment. Drop back down and continue along the path. Battle more of the guards and find the two chests containing a Fleeting Figment and a Royal Cake by the hexagonal platforms. Find the chest at the foot of the hexagonal platforms for a Potion. After the scene, defeat the area's Nightmares and collect the two treasures on either side of the raised center for a Drop-Me-Not and Block-it Chocolate. Save at the Save Point before boarding the Recognizer to the Docks.
