Country of the Musketeers

Country of the Musketeers is a world that is featured in Kingdom Hearts 3D: Dream Drop Distance. It is based on the direct-to-video Disney film Mickey, Donald, Goofy: The Three Musketeers, and notable for being the first world in the series to originate from a direct-to-video movie instead of a film from the Disney animated features canon.

Like Timeless River and Symphony of Sorcery, Country of the Musketeers is set in the past, although at a later period, and focuses on Mickey's earlier adventures as a Musketeer with Donald and Goofy, and is one of the worlds submerged in sleep that must be awakened.

Between Kingdom Hearts Birth by Sleep and Kingdom Hearts
Sometime after Terra-Xehanort's descent into darkness, his heartless, Ansem, Seeker of Darkness, attacked many worlds, including Country of the Musketeers, and swallowed them into the darkness. Though it was restored after Sora defeated Ansem and destroyed the End of the World, Country of the Musketeers remained in a state of deep sleep instead of returning to the Realm of Light, plagued by Nightmare Dream Eaters.

Kingdom Hearts 3D: Dream Drop Distance
The world was first announced in a December issue of V Jump, and it features Mickey, Donald, Goofy, Pete, Minnie, and the Beagle Boys in their attire from the movie.

In the Jump Festa 2012 trailer, it depicts Sora riding atop of a carriage, protecting it from a Tyranto Rex. Other scenes shows Riku rescuing Princess Minnie being held captive inside a treasure chest.
