Shrinkenstein was an industrial film made by Henson Associates for Pak-Nit products in 1965 which spoofs the story of Frankenstein. The Mad Scientist was voiced by Jerry Juhl; while Jim Henson voiced the monster and hero Pak-Nit. The puppet for the mad scientist was previously used for the Prime Minister in Tales of the Tinkerdee, the Pak-Nit puppet was originally used as Mack in ads for Claussen's Bakery, and the monster was played by the Henson puppet known as Big V.
