All has been well in Wasteland since Mickey helped defeat the Shadow Blot, with all the forgotten characters rebuilding their home. However, a series of earthquakes threatens to undo the work and the world. The Mad Doctor (who survived his defeat and mostly communicates by singing) arrives and asks Oswald to join forces with him to help repair Wasteland. Not trusting the Mad Doctor, Gus, the leader of the Gremlins, and Ortensia, Oswald's wife, contact Mickey Mouse. Mickey once more enters Yen Sid's workshop and takes the magic brush to aid him as he enters Wasteland. Oswald joins up with them in Dark Beauty Castle, explaining the Mad Doctor warned him of the Blotworx - Blotlings piloting mechanical suits - which have taken control of the Beetleworx production. The castle begins collapsing from an earthquake, forcing them to escape; Oswald retrieves his powerful remote en route.
