Kingdom Hearts 3D: Dream Drop Distance/Country of the Musketeers

Sora
Sora arrives in the world just in time to save Musketeer Mickey. Defeat the group of Nightmares and a scene will follow in which Sora persuades the Musketeers to let him join them on their noble quest to protect the princess. You can also view a Flashback (Overnight Musketeers). From where Mickey and the Moogle Shop are, turn left under the stairs and toward the wall. Behind a pillar here is a chest containing Paint Gun: Sky Blue x10. Now head all the way to the back wall on the other side of the area. To the left is a Mega-Potion. Turn back to the right and you should see a staircase. At the top of it is an Ice Dream Cone 2. You can now talk to Mickey to venture on a quest with the Musketeers.

Boss: Tyranto Rex
The Musketeers have a duty to protect the princess, and so are escorting her in her carriage. However, it falls upon Sora to fend off a giant Nightmare that comes chasing after the princess. This boss battle can be difficult if only because Sora has such limited space and can't use a Cure spell on a carriage. But the formula is as simple as can be: attack when the Tyranto Rex comes close, and block with when it charges or throws fireballs. Dodging isn't enough in this case; while Sora can avoid the damage, the carriage can't, and the battle is lost if its damage meter fills up. Get close enough to the edge so you can stop its fire breath before it hits the carriage and time your blocks correctly.

Occasionally, once its health gets lower, it will throw a second fireball right after the first. It can be difficult to tell when this occurs due to the first fireball blocking your vision, so watch the Nightmare carefully; the dual fireball attack is actually beneficial to you if you're able to successfully block them all, as they knock off a good chunk of the Rex's health. It will usually charge into the carriage soon after it throws a fireball. Unfortunately, the damage from the charges can't be blocked completely. In this case, ranged magic spells come in handy. The goal is to defeat the Nightmare before it destroys the carriage. If you don't have spells in your deck, the least you can do is attack right as or after it charges; keep it in a combo so that it takes a while to back off. Once it reaches its last health bar, it will start throwing a spell to stun Sora. Jump over this to avoid being momentarily frozen and pummeled by fireballs. Complete the tedious battle to obtain a Tyranto Rex Recipe.

Tower
Despite all of Sora's efforts, the Beagle Boys arrive to knock him off the carriage and escape with the princess. Following the failed mission, the Musketeers find the empty carriage and agree to search for the missing princess. Move forward and defeat the group of Nightmares along the way. The northern path ends at a wall with a dead tree by it; before turning to continue, use Flowmotion to get up this wall and open the chest containing a Shield Cookie 2. Before jumping back down, you should see a higher ledge across the road. Use Flowmotion to get to it and obtain Firaga. Continue up the road, defeating the second group of Nightmares along the way, and head toward the tower, but don't get on the bridge just yet. Drop down to the left of it and open the chest for a Dream Candy. Follow the ledges back up and cross the bridge to enter the Tower.

Defeat the Nightmares that spawn and follow the stairs up until you reach a landing. More Nightmares will spawn here and one of the Beagle Boys will begin throwing barrels at you! Defeat the Nightmares and continue up the stairs. A heap of barrels and planks has apparently been blocking them from reaching Sora; jump over this heap but not before turning right back and opening the chest containing Drop-Me-Not. From here you can jump onto the ledge at the center of the tower and use Flowmotion on the horizontal bar to swing to a birdcage containing Treasure Goggles. Use Flowmotion to get back to your previous location and jump over or dodge the barrels during your ascent. The Beagle Boy will flee once Sora reaches the top of the stairs. Open the chest at the back of the room for an Ice Dream Cone 2 and continue up the next staircase for a boss battle.

Bosses: Beagle Boys
After protecting a carriage against Tyranto Rex, this boss battle should be extremely easy. The Beagle Boys attack quickly and ferociously but only when they get close. Using spells or Flowmotion attacks is very effective and should result in an easy win. If you opt for close range, your Dream Eaters can distract the other two Beagle Boys well enough that you can simply focus on one. Though you can't deplete their health completely, knocking them out is enough in this case. Defeat all three of them to trigger a scene. All is well for the Musketeers, until a conspiracy is uncovered...

Mont Saint-Michel
Sora gathers the Musketeers for one last and very important quest. Examine the gate and select the shore. Follow the path until you get to a large area with a mass of trees in the center. Defeat the Nightmares that spawn here and head into the cave to the left for Paint Gun: Blue x10. Continue on down to the beach and defeat the Nightmares that spawn. Before going for the boat, make a right turn and go back into an area where you should find some more Nightmares and a chest containing a Dream Candy. Examine the boat to leave for Mont Saint-Michel.

Head left from the Link Portal on the map, then down until you reach a staircase that leads to a locked door. Use Flowmotion to get up the wall above the door and open the chest for a Fleeting Fantasy. Drop back down and head north on the map. Nightmares will spawn at a fork in the road. There's a visible chest up ahead but all it contains is another Nightmare. Go left instead and, after defeating the next group of Nightmares, open the chest to the north of this area for a Hi-Potion. Instead of going up the stairs, go south past the wagon and drop down off the ledge. Use Flowmotion to get over the wall directly in front of you; in this area is a large chest containing Sparkga. Return to the staircase and save at the Save Point at the top of it. Before exiting to the next area, drop off to the right and open the chest for a Royal Cake. Now exit to the Dungeon.
