Tips
  • Kammy Koopa has lower Defense than Bowser and tends to heal and mess with stats, so she should be taken out first.
  • Saying yes when the Shadow Queen asks you to be her servant results in a Game Over.
  • Saying no results in the final boss fight.

Final Boss: The Shadow Queen

  • Max HP: 150
  • Attack: 7
