The forth ego in the Jacksepticeye series

The third youngest of Jack's Alter Egos, Dr. Schneeplestein is as optimistic, energetic and confident as his creator, though more prideful at times. He cares deeply for the few friends he has, the closest of which seem to be Jack himself and Chase Brody, and pours all of the knowledge he has into treating them and teaching the viewers, even if some of his knowledge is flawed.
