Final Boss: King Boo | Luigi's Mansion 3 100% Walkthrough "19/19" (No Commentary)

In this part, we follow Mario up to the Roof and rescue Princess Peach only to encounter and battle King Boo. After defeating him, we beat the game. Final Boss: King Boo - 4:15 King Boo has many different attacks he can use. He can create lightning to zap the ground, we must run to the non-purple tiles to avoid it. He can fire off rolling fireballs which we simply move out of the way. He will slam his tongue on the ground where we're standing, so we need to keep moving. Lastly, he'll throw a giant spikeball at us which will break open to reveal bombs. We'll need to suck up a bomb and fire it into King Boo's mouth to stun him, then have both Luigi and Gooigi grab him and slam him three times to damage him. From here, King Boo will split into two and repeat the phase, but he will add one new attack. The two boos will now have a rolling tongue attack that we will have to carefully move under to avoid. When they toss the giant spikeballs, only one will contain bombs and we must shoot a bomb into the real King Boo's mouth to damage him (The real one's eyes will always be showing through the battle, while the fake ones will go dim here and there). After damaging King Boo a second time, he will split into three and add yet another attack. This time, he will make it rain about 20 Bombs at once and we will need to blow them away from us before they explode on us. After damaging him one last time, we will capture him and beat the game!
