Go Behind-the-Scenes of 'Epic Mickey 2'

After watching this 3.5 minute video about the making of Disney Epic Mickey 2: The Power of Two, I have just one question. How does Oswald the Lucky Rabbit get his ears to spin like helicopter blades? ‘Cause that’s a handy skill to have.
In this video, Warren Spector and his team at Junction Point tell you about the changes and improvements being made to the franchise with this second game. Among them: two-player co-op, an upgraded camera system, next-generation graphics (for Xbox 360 and PS3), voice actors, and more.
Sadly, there’s no mention of the original songs that the on-screen characters will periodically break into during the game. Perhaps they’re reserving that feature for a behind-the-scenes video of its own; it’s certainly worthy of one. I just can’t imagine how they’re going to make that work.
