The Beauty Transfer Machine is a machine created by Klungo that appeared in the video game; Banjo-Kazooie. It is a machine designed to transfer the beauty of one person, and giving it to another person, while at the same time, transferring the ugliness of one person, and giving it to the other person. Gruntilda was planning on using this device to steal Tooty's beauty and give the beauty to herself, and give Tooty her ugliness.
After Gruntilda was informed by her Dingpot, that Tooty was the fairest and most beautiful person in the world, she would never tolerate it. So Grunty decided to kidnap Tooty so she could steal her beauty. After successfully kidnapping Tooty, Gruntilda placed Tooty in the Beauty Transfer Device. Gruntilda then processed into the in device. If the player gets a game over, the device will successfully switch Grunty's ugliness with Tooty's beauty, and vice-versa. Fortunately, both Banjo and Kazooie managed to rescue Banjo's little sister and preventing Grunty from stealing Tooty's beauty. It is unknown what happened to the device after Gruntilda was defeat, though it is likely that it was destroyed during the destruction of Grunty's Lair.
