Epic Mickey 2: The Power of Two is currently in development for PlayStation 3, Xbox 360 and Wii, producer Warren Spector has announced.
Speaking in an Associated Press interview, Spector revealed that, unlike the 2010 original, the game will be a musical with full voice acting for all characters.
"I'm such a geek about musicals," he said.
"I love the co-op and next-gen stuff, but for me, when a character breaks into song, which they do on a regular basis in this game, it's magic."
You can also expect drop-in, drop-out co-op, with one player controlling Mickey and his paintbrush, and the other playing as Oswald the Lucky Rabbit, who wields a remote control with which he can manipulate electricity.
"You can sit down at any time with a friend who is playing as Mickey, and you can take control of Oswald," explained Spector.
"If you're playing as a single player, Oswald will be there every second of the game. He's not just a multiplayer character. He's a helper, whether you're playing alone or with a friend or family member."
The other key focus for Spector and his team at developer Junction Point is the game's camera - much criticised in the original. He promised a much more user-friendly experience this time around.
"We've had a team working on the camera from literally the day we finished the first game. They'll be working on it until the day we ship the second game," he said.
"(There have been) over 1000 specific changes made to the camera. Our goal is that you will not have to touch the manual camera controls even once to play through the main story path of this game."
Spector didn't reveal much detail about the sequel's plot other than that it will see Mickey return to Wasteland. Similarly, no word on a release date or on the 3DS version rumoured earlier this week.
Its Wii-only predecessor picked up a middling 6/10 back in November 2010.
"For all its big ideas, Disney Epic Mickey never quite weaves its disparate strands into a convincing whole. Its conceptual ambition is let down by merely adequate mechanics, and Mickey himself remains a rather abstract figure at the centre of it all," read Eurogamer's Epic Mickey review.
