The Skool Principal has never been fully seen, appearing only as a mysterious silhouette. He is always seen stroking a pet beaver in his lap, which in turn pets another small thing. He appeared in "The Voting of the Doomed".
It was mentioned in the episode "Vindicated!" that there was another counselor before Mr. Dwicky. When asked about him, Mr. Dwicky said that "something horrible" had happened to him, at which point a voice coming from the ventilation was heard saying "Help... Me..." The former counselor was voiced by Jhonen Vasquez, and the scene was voted one of the "creepiest" moments of the series.
