You go to Fountain Head, hire Allan Bow or Fineas, dump the Fizbin in his backpack, and then dismiss him.You can use the same trick with the Power Orbs. There are 31 Power Orbs, and as soon as you give any king 11 of them, the other two castles are ruined. The thing is, you cannot give the Orbs one by one. If there are 3 in your backpack and you go up to one of the kings, he'll take all three, and that's tough if you're carrying 3 orbs and each of the kings have got 8. So what you do is you hire (say) Fineas, give him one of the orbs and then give 2 to a king of your choice, so you can get the benefit of all the orbs' experience without losing access to any castle.
