The Evil Enlarging Machine was a sentient machine created by Ludwig von Drake.
Created by Ludwig von Drake to help Minnie Mouse in the creation of a giant cake for Mickey Mouse's birthday, this enlarging-ray-machine became sentient and evil after Minnie cranked it up too high. It attached itself to her, feeding a monomaniacal obsession with making everything around her larger. However, Minnie's realization (helped by Mickey) that only good intentions matter, not the size of the present, overloaded its circuits and it ceased to function.
Behind the scenes
The Evil Enlarging Machine appears in the 2018 cartoon Surprise! as its main antagonist.
