Professor Tetti-Tatti is a villain from the 1946 film Make Mine Music. He is the primary antagonist in the segment, "The Whale Who Wanted to Sing at the Met." He is a ship captain intent on killing Willie the Sperm Whale, who he believes is nothing but a monster. Willie is actually a kind, gentle creature who only wants to become famous for his voice. Willie dreams of singing in the opera one day and practices for other creatures in the sea. When Tetti-Tatti and his crew finally find Willie, the crew is captivated by Willie's voice and begs the captain not to kill him. Intent on the fact that he is still a monster, Tetti-Tatti kills Willie anyway. The narrator softens the blow by telling the audience not to be mad at Tetti-Tatti because he simply didn't understand, and also that Willie continues to sing in heaven.
