In BattleEdit

  • Big Boo Boss in Intangible House
  • Big Boo Boss in The Cursed Mansion
  • Big Boo Boss in Four-Room House

Big Boo Boss will fly around the screen. When he gets hit, he turns invisible, becoming invincible to any hit.


Intangible HouseEdit

In order to deal damage, the player must hit the Boo with a blue block. After three hits, the Boo will be defeated.

The Cursed MansionEdit

Before fighting the Boo, the player must collect all the Dragon Coins. Hit the Boo first with a Koopa shell, then the two blue blocks (spin jump the regular bricks to access them).

Four-Room HouseEdit

Instead of using blue blocks, the player must used various objects that are throw-able: a P-Switch, key, and Koopa shell (must be unlocked).
