I have also had trouble doing this. You must first wait until he shoots a spike ball. When he does, pick it up with the vacuum and shoot the spike ball at him. Then I think he flies out and has 300 health. Start sucking up like a normal boo and repeat this process until he is dead and you get his crown gem and save Mario.
King Boo is the last boss
if your talking about super Mario 64 ds there are 2 luigi paintings (1 in the castle and 1 in boo's mansion) the 1 in the castle is fake and the 1 in boo's mansion is the reals one that u can enter by jumping into it.
same
That all depends on which boo you are talking about. If its king boo, wait until he hits the ground and make him move under the round shadow and then try to capture him when he gets hit with the spike ball. If is a regular boo use the dark light device to find him and suck up his tongue.
You beat bowser( or king boo) by when bowser blows black spikes that explodes that comes from bowser's mouth and you vaccum one and when it flashes red then throw it to bowser and king boo will come out and just take king boo's life and keep getting black spikes until you vaccum all his lifes
King Boo is bowser
Whenever Bowser shoots the giant spike balls, you suck them up with your poltergust 3000 (vacuum cleaner) and shoot them at bowser's head. Then King Boo comes out and you suck his hp out, and beware of Bowser shooting ice at you. Keep doing this and you will eventually beat him.
Neither. It is believed to be a sequel to Super Mario Sunshine because the first time Mario and King Boo meet is in that game. In Luigi's Mansion, King Boo says he is getting revenge on Mario.
To get King Boo, beat special cup in 1st place. But, there is no boo.
yeah its for gamecube luigi has an awsome kik but vacume to suk up the boo and save Mario i think its called luigis mansion. Luigi is in a game on the SNES called Mario Is Missing. There is one on gamecube called Luigi's Mansion also.
its where the picture of king boo goes
its where the king boo pic will go
