Oobleck's trademark characteristics are his extreme hyperactivity and his love for coffee, tea or some other stimulant. Not only does he frequently "glide" about in class at incredible speeds, he also speaks very rapidly. When moving, he often appears as a blur or moves so quickly that his legs appear stationary. Bartholomew displays a great deal of enthusiasm for all of his work, including his duties as a Huntsman. He also clearly relishes his role as a mentor and instructor.
