Boom-Boom's socks

Boom-Boom's socks are an item in Koopa Capers. They are a pair of dirty sweat socks labeled "BOOM-BOOM." After Luigi unlocks one of the doors with a key, he enters a big chamber carved from the lava cliff, where he detects an extremely unpleasant odor coming from Boom-Boom's socks. Deciding to take them with him, Luigi wraps them in a plastic bag and pockets them. He later finds Wendy O. Koopa stirring grorange glop in a metal pot in another room, and she tells some Koopa creatures to find one of the socks to add to the pot. Bowser and the other Koopalings enter the room and chase Luigi, eventually surrounding him. Luigi then reaches into his pocket. If he has the socks, he pulls them out, removes the plastic bag from them, and waves them over his head, filling the room with a stench that makes everybody, including Luigi, cover their nose and gasp for air. However, the smell does not stop Bowser and the Koopalings. Bowser suggests that Luigi put down the socks, but Luigi refuses, throwing both socks into the pot and triumphantly shouting the potion's recipe's ninth and tenth lines. The room then fills with a thick grorange gas as the pot boils over, causing Bowser and the Koopalings to fall to the floor in a deep sleep. If Luigi does not have the socks, he pulls from his pocket a laser-guided Swiss army pipe threader and plunger (a weapon that looks like a cross between a missile launcher and a big pipe wrench) he put in his pocket in Brooklyn earlier, making the Koopas hesitate. Since their magic wands were thrown into the potion, the Koopalings are defenseless against Luigi's weapon, so they start to retreat. Luigi thinks he can exit the room, but his facial expression says otherwise because he does not want to inadvertently reveal his intentions. Bowser orders the Koopalings to grab Luigi, which they do promptly, then Bowser grabs him and holds him upside down over the pot. Luigi begs for mercy, but Bowser laughs and drops him into the pot, leading to a Game Over.
