The Pacifier from Hell (火炎橡皮奶嘴 Kaen Oshaburi?) is a special pacifier from the Joketsuzoku village that was created to give babies a means of self-defense by functioning as a flamethrower. Its name uses the Chinese characters for "rubber nipple" and the Japanese kanji for "pacifier".
After Mousse obtained the Lens of Invincibility, he used it against Ranma Saotome, forcing the latter to bow down and beg forgiveness from him three times in front of others. Ranma, whose pride had taken a huge hit and was burning for revenge, then issued a challenge to Mousse. However he decided to also use underhanded methods and borrowed several items from Cologne. Like the Lens of Invincibility, these were used by the weak to defend themselves, and Ranma picked out what he felt were the most despicable. One of these was the Pacifier from Hell, which he used as the third weapon in the duel to breathe fire on Mousse before kicking him into the air.
