One character in this work claims to have rescued 
One character in this work claims to have rescued the protagonist from a massive beast, after which the Three Ladies padlock his mouth shut for lying. In another scene, that birdcatcher is forced to swear not to speak to women, but sings about his desire for a wife and pledges himself to an elderly woman, who then becomes young. Those two characters sing the duet "Pa pa pa" after Papageno tries to hang himself. Pamina is given a dagger to kill Sarastro by her mother, the Queen of the Night in the aria Der Hölle Rache. For 10 points, name this work in which Prince Tamino receives the title instrument, the last opera by Mozart.
