The Human to Pet Mind Transplant Device is one of the devices found in Iago Heterodyne's Red Playroom. It is first mentioned as Agatha and Gil are Tarvek Sturmvoraus. Gil brings it up as a way to prevent "death trauma memory loss".
Violetta suspects that Tarvek has already had his brain removed when he calls for her, however this is not the case.
Did anyone notice Violetta carrying a brain in a jar, labeled?
