While it is noticeably slowed down during a Genocide Route, its speed changes after certain actions on every route. Snowy plays slowly after the protagonist meets Sans and Papyrus, but its speed increases after the electric maze puzzle and the junior jumble puzzle. Its speed also differs after Papyrus realizes the protagonist is a human.
