Calvin in notebook paper form is a minor alter ego of Calvin's that appeared in a single Sunday strip. In the strip, Calvin finds himself on a piece of notebook paper fill with his doodles. He "roars" around the page in a tank blowing up his school and attempts to blow up Miss Wormwood. However, she was too "big and mean." At the end of the strip Miss Wormwood confiscates the drawing, sarcastically calling him "Leonardo". Calvin remarks "The arts are always the first to go in public schools."
