Amadeus Wolfgeist will start by lifting all the chairs in the room and tossing them at us, so simply run non stop to dodge these. Afterwards, he will summon some dancing ghosts to attack us. To deal with them, we suck up the masks on their faces, then deal with them as usual. From here, he possesses his piano and attacks us himself. We must dodge his dive bombing by staying out of the spotlight, and his piano keys by staying in the gaps. Once he just onto the stage and tosses bombs at us, we must suck one up and shoot it into the piano to stun him. From here, we Suction Slam the piano to get him out, then stun and damage him. We repeat the process until he is captured and we obtain the 6F Elevator Button.
