Spook generally has a smaller role in the series and less to do than the other characters, but in this episode he has more spoken lines as well as three separate key points of business in the actions that take place at different parts of the story. The color of his fur would also vary, usually being olive green, but at other times a light brown. Leo De Lyon provided the voices of both Spook and Brain as well as miscellaneous other characters appearing in various episodes.
