If I had to guess, I'd say WoZ is much like LOTR in that to Destroy the Ring you just need to play the 3 movie multiballs.
In WoZ, you need to start Emerald Multiball, Rescue Multiball, a Munchkin Mode, and Fireball Frenzy. Then you can start Wicked Witch battle mini wizard mode.
Valinor=Somewhere over the rainbow.
