Has absolutely no sense of humor. Always on the clock for his tasks. Ony Dr. Toxic and Scotch talk to him after they finished their tasks. He only considers Dr. Toxic and Scotch his true friends.
As a Crewmate he goes right for what seems to be the hardest tasks first,then finishes with the easier tasks last. His favorite task is apparently the Samples Task in Medbay
As the Impostor, Dr. Snowball hangs around Med Bay because of the famed "watch me do medbay scan" thing. He always skips the first two voting sessions because he "claims" he doesn't know who the Impostors are.
