Associated Quests

  • Rebuild the statues to close the pit. You cannot continue until you do; you cannot retreat unless your team is broken.
  • Defeat the three Witches. You cannot continue until you do; you cannot retreat unless your team is broken.
  • Defeat Hades, the Lord of the Underworld. You cannot retreat unless your team is broken. There are two Buildies that provide healing hearts and an electrical field that damages enemies.


These are also known as minibosses; they usually have distinct names and the red and orange circle around them.

Character Points

  • Smash 50 Witches as Cyclops, Waiter or Wizard (50 Points each). The Three Witches count towards this.
  • Build 15 Mythology Statues as Fortune Teller, Plumber or Scientist (50 Points each). Note: The statues you build to close the pit (see above) do not count, but the buildies used to fight Hades do (the one on the right counts as 1 build but two statues!).
  • Smash 25 Minotaur Statues as Jester, Motorcycle Mechanic, Policeman, Rock Star or Warrior Woman (50 Points each).

Story Quests



  • Roman Emperor parts were moved to Space World. They were replaced by Decorator parts.
