Beauty Steal Machine

The Beauty Transfer Machine is a machine that Gruntilda attempted to use in Banjo-Kazooie to transfer her ugliness into Tooty and Tooty's beauty into herself. It consisted of two pods, one for each person to be placed in. With the press of a button by her henchman Klungo, the ugliness and beauty of each subject would be transferred to the other. However, Gruntilda's evil motives were foiled by Banjo and Kazooie and Tooty was saved.

Trivia
The machine's design may be a reference to the 1958 movie The Fly, and its sequels and remakes in later years.
