Amazing cardboard

Calvin often uses cardboard boxes for his different inventions, such as the Transmogrifier and the Cerebral Enhance-O-Tron. It is thought by some that at least one box was the packaging for the Chocolate Frosted Sugar Bombs beanie. This, however, is unlikely, as the beanie box is significantly smaller than any of Calvin's inventions, and the Transmogrifier was invented before the beanie was ordered. Every box has taken Calvin and Hobbes on an adventure.
