Disney Epic Mickey 2: The Power of Two

All has been well in the Wasteland since Mickey Mouse saved it from destruction by the Shadow Blot, with the world's inhabitants beginning its restoration. However, a series of earthquakes have been occurring lately. The Mad Doctor, who now mostly communicates by singing, arrives and speaks of how he has reformed and requests Oswald to join forces with him in order to save Wasteland from this new threat. Not trusting the Mad Doctor, Gus, the leader of the Gremlins, and Ortensia, Oswald's wife, contact Mickey for assistance. Getting the transmission after being awoken from bed, Mickey enters Yen Sid's workshop once more and takes back the Magic Paintbrush to aid him as he returns to Wasteland. Oswald joins up with them in Dark Beauty Castle, explaining the Mad Doctor warned him of Blotworx - Blotlings piloting Beetleworx-like battle mechs. The castle begins collapsing from an earthquake, forcing them to escape while Oswald retrieves his remote en route.
